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 this hypothesis test.
-z-statistic = 2.00. p-value = ?
A) 0.0228
B) 0.9332
C) 0.9545
D) 0.9772

Quizplus · Accepted Answer

The p-value for a z-statistic of 2.00 in a one-tailed test (p < 0.40) is found by looking at the standard normal distribution table, which gives 0.9772 for the area to the left of z = 2.00.
