Question

Assume that the significance level is

alpha equals 0.1α=0.1.

Use the given information to find the​ P-value and the critical​ value(s).

The test statistic of

zequals=negative 0.92−0.92

is obtained when testing the claim that

p less than 0.6p<0.6.

Answer 1

We have , Hypothesis : Vs

Since , the test is one (left) tailed test.

Therefore ,

The critical value is ,

; From Standard normal distribution table

The p-value is ,

p-value=

; From Standard normal distribution table

OR The Excel function for p-value is ,  =1-NORMDIST(0.92,0,1,TRUE)
