TI-NspireTM Technology Corners
Texas Instruments released the new TI-Nspire CX in March
2011. The new handheld no longer has an interchangeable TI-84
­faceplate; however, the body of the Nspire CX is much slimmer
and its display is in full color. When you click ctrl menu and arrow down to Color, there are several options available: Line Color,
Fill Color, and Text Color. If you choose the Fill Color option, a
color palette will appear. Then you can select the colors you want
for your graphs. This feature is quite useful when displaying multiple graphs. When creating a bar graph, the CX even allows you to
change the color of each bar!
The keystrokes used for the new CX are the same as for the TINspire Touchpad. The keystrokes for the older Nspire “clickpad”
are still different in some ways; therefore they are still shown in
parentheses when needed.
Start by updating your device’s OS to ensure that your handheld has full capabilities. Go to education.ti.com and search under
Downloads S Software, Apps, Operating Systems… to download
the latest version of the OS. If you have the TI-Nspire computer
link software, you should be asked automatically to update your
handheld’s OS.

United States into the list. The data can be found on page 33.
3. Insert a Data & Statistics page: press ctrl I , arrow to Add
Data & Statistics, and press enter .
• Press tab and Click to Add Variable on the horizontal axis
will show the variables available. Select foreignbrn.
• The data should now move into a dotplot. Notice the organization of the graph. Even though the data look “lopsided” in
some places, you should consider the dots as being directly
above each other in each column.
4. To make a better graphical display, let’s move the data into a
histogram. Use the Navpad to position the pointer in an empty
space within the graph. Press ctrl menu and select Histogram.
You will now see the data move into a histogram.
You can now position the pointer ( ) over each bar to examine
the classes. The pointer will become an open hand

5. From z-scores to areas, and vice versa
Finding areas: The normcdf command on the Nspire can be used to
find areas under the Normal curve. The syntax is normalcdf (lower
bound, upper bound, mean, standard deviation). Let’s use this command to confirm our answers to the examples on pages 116–118.
1. On the Home screen, select the Calculate scratchpad. This will

a document you are working on or about adding an unneeded
page to that document.
value corresponding to a given percentile in a Normal distribution.
For this command, the syntax is inv Norm(area to the left, m, s).
3. Let’s start with a “clean slate” by clearing the entries on our
page. To do this, press menu S Actions S Clear History.
Your scratchpad should now be blank.
What is the 90th percentile of the standard Normal distribution?
• Press menu S Statistics S Distributions S Inverse Normal.
A dialogue box will appear. Type the numbers in the dialogue
box as shown. To enter the numbers, tab between the entry
boxes. When the last number is entered, tab to OK and press
enter .
What proportion of observations from the standard Normal
­distribution are greater than –1.78?
Recall that the standard Normal distribution has mean 0 and
standard deviation 1.
2. On the Calculate scratchpad, press menu S Statistics S
­Distributions S Normal Cdf. In the dialogue box that appears,
type the numbers shown. To move between the drop-down boxes, press tab after typing each number. When the last number
is entered, tab to OK and press enter .
The proportion should now be displayed on the main screen.
Note: We chose 10,000 as the upper bound because it is many
standard deviations above the mean. These results agree with our
previous answer using Table A: 0.9625.
What proportion of observations from the ­standard Normal
distribution are between –1.25 and 0.81?
These results match our previous answer using Table A.
6. Normal probability plots
We will use the state unemployment rates data from page 122 to
demonstrate how to make a Normal probability plot for a set of
quantitative data.
1. Insert a New Document by pressing ctrl N .

10. Choosing an SRS
The TI-Nspire has a function called randSamp that will randomly
select individuals for a sample with or without replacement from
a population.
1. Check that your calculator’s random number generator is
­working properly.
• Open the Calculator Scratchpad by pressing
(or
A on the keypad).
• Type randint(1,1750) and press enter .
• Compare results with your classmates. If several students have
the same number, you’ll need to seed your calculator’s random
number generator with different numbers before you proceed.
Type randSeed, press
(to insert a space), type < last four
digits of your phone number> and press enter . Done should
appear. Now your calculator is ready to generate numbers that
are different from those of your classmates.
Let’s explore what the calculator can do using the random variable X = Apgar score of a randomly selected newborn from the
example on page 349.
1. Insert a Lists & Spreadsheet page. Press ctrl I , arrow to Add
Lists & Spreadsheet, and press enter .
• Name column A apgar and column B apgrprob.
• Enter the values of the random variable (0 − 10) in the apgar
list and the corresponding probabilities in apgrprob.
2. Graph a histogram of the probability distribution.
• Insert a Data & Statistics page. Press ctrl I , arrow to Add
Data & Statistics, and press enter .
• Press ctrl menu and select Add X Variable with Summary
List. Press enter and a dialogue box should appear. a­ pgar
should be in the X List and apgrprob should be in the

13. Binomial probability on the calculator
There are two handy commands on the TI-Nspire for finding
binomial probabilities:
binomPdf(n,p,k) computes P(X = k)
binomCdf(n,p,k) computes P(X ≤ k)
3. To calculate the mean and standard deviation of the random
variable, use one-variable statistics with apgar as the Data List
and apgrprob as the Frequency List.
• Press ctrl to go back to the Lists & Spreadsheet page.
• Press menu S Statistics S Stat Calculations S OneVariable Statistics.
• Make sure your X1 List, Frequency List, and 1st Result Column
have the variables/values shown (you can press the down arrow in the drop-down boxes to access the variable names and
type C for 1st Result Column). tab to OK and press enter .
You will need to open the Calculator Scratchpad (press
or
A on the clickpad). These two commands can be found
in the Distributions menu within the Statistics menu. You can
access them by pressing menu S Statistics S Distributions. A
dialogue box will appear. Input n (the number of observations), p
(probability of success), and k (number of successes).
For the parents having n = 5 children, each with probability
p = 0.25 of type O blood:
P(X = 3) = binomPdf(5,0.25,3) = 0.08789
To find P(X > 3), we used the complement rule:
P(X > 3) = 1 − P(X ≤ 3) = 1 − binomCdf(5,0.25,3)
= 0.01563
• The statistics should now be displayed in your Lists & Spreadsheet page.
Of course, we could also have done this as
P(X > 3) = P(X = 4) + P(X = 5)
= binomPdf(5,0.25,4) +
binomPdf(5,0.25,5)
= 0.01465 + 0.00098 = 0.01563
On the TI-Nspire, you can also calculate using
P(X > 3) = P(X = 4) + P(X = 5)
= binomCdf(5,0.25,4,5)
= 0.01563
12. Binomial coefficients on the calculator

To calculate a binomial coefficient like a b on the TI-Nspire,
2
proceed as follows. Open the Calculator Scratchpad by pressing
A on the clickpad). Press menu S Probability
(or
S Combinations, and then enter . nCr( will appear. Complete
the command nCr(5,2) and press enter .
14. Geometric probability on the calculator
There are two handy commands on the TI-Nspire for finding
geometric probabilities:
geomPdf(p,k) computes P(Y = k)
geomCdf(p,k) computes P(Y ≤ k)

menu within the Statistics menu. You can access them by pressing
menu
S Statistics S Distributions. A dialogue box will appear.
Input p (probability of success) and k (number of trials to get the
first success).
16. Inverse t on the calculator
For the Lucky Day Game, with probability of success p = 17 on
each trial,
P(Y = 10) = geomPdf(1/7,10) = 0.0357
To find P(Y < 10), use geomCdf:
P(Y < 10) = P(Y ≤ 9) = geomCdf(1/7,9) = 0.7503
The TI-Nspire allows you to find critical values t* using the
inverse t command. As with the calculator’s inverse Normal command, you have to enter the area to the left of the desired critical
value. Let’s use the inverse t command to find the critical values
for parts (a) and (b) in the example on page 513.

24. Two-sample t tests on the calculator
Technology gives smaller P-values for two-sample t tests than the
conservative method. That’s because calculators and software
use the more complicated formula on page 640 to obtain a larger
number of degrees of freedom.
Start by entering the sample data into a column in a Lists &
Spreadsheet page. Name column A calcium and enter the Group
1 data. Name column B placebo and enter the Group 2 data.
Then do the test:
• Press menu S Statistics S Stats Tests S 2-Sample t Test.
• In the first dialogue box, select Data in the drop-down menu.
tab to OK and press enter .
• In the next dialogue box, enter the values shown, tab to OK ,

5. To see if a power model fits the data:
• Using the same Data & Statistics page, change the horizontal
axis to lndistance.
• If this relationship looks linear, then a power model is
appropriate.
6. If a linear pattern is present, calculate the equation of the leastsquares regression line:
• In the spreadsheet, press menu S Statistics S Calculations S Linear Regression(a + bx).
• In the dialogue box, select lndistance for X List, lnperiod for
Y List, and enter the rest of the values as shown. tab to OK

7. Construct a residual plot to look for any departures from the
linear pattern.
• Insert another Data & Statistics page.
• For the horizontal axis select lndistance. For Ylist, use the
stat.resid list stored in the calculator.
8. To make a prediction for a specific value of the explanatory variable, compute log(x) or ln(x), if appropriate. Then do f1(k) to
obtain the predicted value of log y or ln y. To get the predicted
value of y, do 10^Ans or e^Ans to undo the logarithm transformation. Here’s our prediction of the period of revolution for
Eris, which is at a distance of 102.15 AU from the sun.
