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,
