Question

In past years, the proportion of engineering students at the local college who did not own a
calculator was 0.15. Angelina believes the proportion of current population of engineering
students who do not own a calculator is lower. She randomly selects 55 students and finds that
0.05 and calculates a p-6 of them do not own a calculator. She uses a significance level of a -
value of 0.198. What null and alternative hypothesis did Angelina use for this test, and what
conclusion can she make? Note: The item below has been reviewed and is scheduled to be
updated. All students will receive full credit for any response to the following.
(1 point)
H0: p=15
He: p > 15
Angelina fails to reject the null hypothesis because the p-value is greater than the significance level.
H0: p=0.15
He: p<0.15
Angelina rejects the null hypothesis because the p-value is greater than the significance level.
H0: p=15
He: p<0.15
Angelina fails to reject the null hypothesis because the p-value is greater than the significance level.
H0:   µ= 0.15
He:   µ<0.15
