9. A marketing manager wants to know whether loyal customers would buy their
toothpaste if the price would rise with 10%. He formulates the following hypotheses:
H0: Loyal customers are neutral or positively inclined to buy our toothpaste in case of
a price increase of 10%.
Ha: Loyal customers are negatively inclined to buy our toothpaste in case of a price
increase of 10%.
He asked 100 people the following question:
If the price of the toothpaste you are currently using would increase with 10%, how likely
would it be that you would buy it next time you need toothpaste?
Very likely
Neutral
Very unlikely

B. A Chi-square test for independence.
C. An independent samples t-test.
D. A one-sample t-test.

* Question 2: What have you bought on the Internet during the past 6 months? (more than

B. 4 columns.
C. 6 columns.
D. 8 columns.
(11.) Consider the following screenshot:
Which of the following set of null and alternative hypotheses could be tested if you know
that the variable ‘Appreciate’ measures ‘how much do you appreciate the current course
scheduling procedure’ on a 5-point Likert scale (1=dislike a lot, 2=dislike, 3=neutral,
4=like, 5= like a lot)?
A. H0: Students have a neutral appreciation regarding the course scheduling procedure.
Ha: Students do not have a neutral appreciation regarding the course scheduling
procedure.
B. H0: Students have a neutral or negative appreciation regarding the course scheduling
procedure.
Ha: Students have a positive appreciation regarding the course scheduling procedure.

procedure.
Ha: Students have a negative appreciation regarding the course scheduling procedure.

(12.) Emma wants to find out if the time that someone spends in the first round of
registration differs between males and females. She has the following set of hypotheses:
H0: There is no difference in the time that males spend in the first round of registration
compared to the time that females spend.
Ha: There is a difference in the time that males spend in the first round of registration
compared to the time that females spend.
She measures the time that someone spends with an open question where respondents
could indicate the number of minutes spent in the registration, and asks respondents
whether they are male or female.
12. Which is the most appropriate test to do with these variables (no recoding)?
A. Chi-square for independence.
B. ANOVA.
C. Independent samples t-test.
D. Regression.
(13.) Consider the set of hypotheses in question 12. If the questionnaire question that was

most appropriate test?
A. Chi-square for independence.
B. ANOVA.

D. Regression.
(14.) Emma tests the following set of hypotheses with an independent samples t-test:
H0: Students that spend more than 15 minutes in the first round of registration give the
same or a higher evaluation for the current course scheduling procedure than students that
spend 15 minutes or less.
Ha: Students that spend more than 15 minutes in the first round of registration give a lower
evaluation for the current course scheduling procedure than students that spend 15 minutes
or less.
She gets the following output:
Which of the following statements is true?
A. One cannot assume equal variances because the p-value of the Levene’s Test for
Equality of Variances is .786.
B. One cannot assume equal variances because the p-value of the Levene’s Test for

of Variances is .393.
(15.) Which of the following statements is true?
A. The evaluation of students that spend > 15 minutes is not significantly different from the
evaluation of students that spend <= 15 minutes because the p-value of the t-test is .450.
B. The evaluation of students that spend > 15 minutes is not significantly different from the
evaluation of students that spend <= 15 minutes because the p-value of the t-test is .225.
C. The evaluation of students that spend > 15 minutes is not significantly different from the
evaluation of students that spend <= 15 minutes because the p-value of the t-test is .449.
D. The evaluation of students that spend > 15 minutes is not significantly different from the
evaluation of students that spend <= 15 minutes because the p-value of the t-test is .2245.
