Suppose you carry out a significance test of H0: μ = 7 versus Ha: μ ≠ 7 based on sample size n = 28 and obtain t = 1.45. Find the p-value for this test. What conclusion can you draw at the 5% significance level? Explain.

Possible answers:
The p-value is 0.0793. We reject H0 at the 5% significance level because the p-value 0.0793 is greater than 0.05.
The p-value is 0.0793. We fail to reject H0 at the 5% significance level because the p-value 0.0793 is greater than 0.05.
The p-value is 0.4207. We fail to reject H0 at the 5% significance level because the p-value 0.4207 is greater than 0.05.
The p-value is 0.1586. We fail to reject H0 at the 5% significance level because the p-value 0.1586 is greater than 0.05.
The p-value is 0.1586. We reject H0 at the 5% significance level because the p-value 0.1586 is greater than 0.05.
