In a test of H0 100 against H1 100 a sample of size 80 prod

In a test of H0: = 100 against H1: 100, a sample of size 80 produces z = 0.8 for the value of the test statistic. The p- value of the test is thus equal to:

A) 0.20 B) 0.40 C) 0.29 D) 0.21 E) 0.42

Solution

n a test of H0: = 100 against H1: 100, a sample of size 80 produces z = 0.8 for the value of the test statistic. The p- value of the test is thus equal to 1-0.7881=0.2119.
