Assume that the significance level is a 005 Use the given i

Assume that the significance level is a = 0.05, Use the given information to find the p-value and teh critical value. With H₁:P not equal to 1/2, the test statistic is z = -1.36

P-Value = ______

The critical value is/are _______

Solution

It is a two-tailed test.

So the p-value= 2*P(Z<-1.36) = 0.1738 (from standard normal table)

Given a=0.05, the critical values are Z(0.025) = -1.96 or 1.96 (from standard normal table)
