Question
A Rutgers University professor claims that there is no significant difference between proportion of female (f) and male students (m) of the university who exercise at least 15 minutes a day. What would be a proper conclusion if he collects data, conducts hypothesis test, and finds z=3.42. Use = 2%.
A. Reject H0. There is a significant difference.
B. Reject H0. There is no significant difference.
C. Fail to reject H0. There is a significant difference.
D. Fail to reject H0. There is no significant difference.
A. Reject H0. There is a significant difference.
B. Reject H0. There is no significant difference.
C. Fail to reject H0. There is a significant difference.
D. Fail to reject H0. There is no significant difference.
Explanation / Answer
if Z = 3.42 we will find the probability for that value of Z in the tables of Z distribution
for Z = 3.42 p value is 0.00001
for alpha = 0.02
alpha / 2 = 0.01
so as you can see p value is lower than alpha /2 so we reject Ho
A. Reject H0. There is a significant difference.
A. Reject H0. There is a significant difference.
