Question

Use the following information for questions:
 A hypothesis test for a population proportion p is given below:
H 0 : p ≤ 0.40
H a : p > 0.40
For each z-statistic, calculate the p-value for the hypothesis test.
-z-statistic =-1.50. p-value = ?
A) 0.0668
B) 0.1469
C) 0.8531
D) 0.9332

Quizplus · Accepted Answer

The p-value is calculated for the alternative hypothesis (p > 0.40) given the z-statistic of -1.50. Since the test is right-tailed, the p-value is the area to the right of z = -1.50, which corresponds to 0.9332.
