QUESTION:

You are given the following hypotheses:

        

         

We know that the sample standard deviation is 8 and the sample size is 20. For what sample mean would the p-value be equal to 0.05? Assume that all conditions necessary for inference are satisfied.

ANSWER:

Step 1 of 2

Given,

Sample size, n = 20

Standard deviation,

P-value = 0.05

Then, the degrees of freedom is,        

        

The critical t-value from the t-probability table corresponding to df = 19 and p-value =0.05 is,

        

The lower tail is,
