Suppose you carry out a significance test of H0aThe p-value is 0.02. We reject H0: μ = 8 versus H: μ > 8 based on sample size n = 25 and obtain t = 2.15. Find the p-value for this test. What conclusion can you draw at the 5% significance level? Explain.
At the 5% significance level because the p-value 0.02 is less than 0.05.
The p-value is 0.02. We fail to reject H0 at the 5% significance level because the p-value 0.02 is less than 0.05.
The p-value is 0.48. We reject H0 at the 5% significance level because the p-value 0.48 is greater than 0.05.
The p-value is 0.48. We fail to reject H0 at the 5% significance level because the p-value 0.48 is greater than 0.05.
The p-value is 0.52. We fail to reject H0 at the 5% significance level because the p-value 0.52 is greater than 0.05.
