Assume that the significance level is 01 Use the given infor

Assume that the significance level is =0.1. Use the given information to find the P-value and the critical value(s). The test statistic of z=1.88 is obtained when testing the claim that p>0.4.

Solution

alpha = 0.1

alpha / 2 = 0.05

looking in the normal distribution table

critical values

Zcritical = +1.64 and -1.64

p-value for Z = 1.88

p value = 0.0301
