1) 60+1.1*120=192
2)
The true mean is either between 45 and 68 or it is not.
We are confident the mean is between 45 and 68 by using a method that is correct 90% of the time.
The true average distance is between 45 and 68 yards with 90% confidence
3) (.46-.82) +- 3.106 .02/sqrt(12) = (-.3779, -.3421)
4) 25 +- 1.99 *8/sqrt(100) = (23.408, 26.592)
5) 35.5 = 1.555 * 700/sqrt(n) n=940.15 so need 941 students
6) Cannot do
7) I see constant variance problems because of the bottle shape
H0: β1 = 0
Ha: β2 ≠ 0
α = 0.05
T98=2.02
p-value = 0.046
(or you could put) 0.02 < p-value < 0.05
Reject the null
We can say there is a relationship between age and time before the iPad is broken.

2x(0.02 < pvalue < 0.025)

Reject the null
We can show that US graduates are different on average from the CSU graduates as far as salary

Skydive
Sky dive while doing a statistical problem on the board
Spiderman style sling a web onto a building to stick a camera then do parkour while it is set to
take pictures
No self respecting statistician would take a selfie
By not taking one. Selfies are overrated
Statisticians don't take selfies, they collect the data of how amny girls take "selfies" with their
starbucks
There is no epic selfie
Depends on what you mean by epic since that word doesn't normally apply to statisticians
Something 12 standard deviations above the mean
By testing the pictures to find the significantly epic one
Two said By calculating the probability for it
Two said With a cool equation
In front of a hill that looks like a normal distribution
In style
While bungee jumping while being confident the bungee cord is safe
On a collapsing bridge
With a building blowing up in the background to test the average amount of explosive needed
Any selfie of a statistician is epic
Doing a backbend that looks like a normal curve
Use regression lines to make a picture of them
Two said Take a selfie while singing from on the stool on the table in front of the class
singing "selfie" by the chinsmokers
Two said Make a giant normal curve with blocks
Since they are rich and famous take it in front of their gold car
Just take a picture of themselves. Statisticians are people too
Use 30 selfies to make a "normal" selfie
With a t-table
Make his face with regression dots
With their phone
With 30 friends so they can finally be normal
While receiving a nobel prize
Take a picture of the population instead of the sample
Take a picture of a tree and then ask the students to calcualate the probability that I'm hidden
behind the tree
In the stat library at the Guiness factory
Find a famous statistician if there are any
In Stats 4220 which is the best class ever!
On the roof of the engineering building
With engineers to make it epic
Give statistics tests
Take a picture of him with the final and send it to all the students
