You are conducting a significance test of H0: μ = 5 against Ha: μ > 5. After checking the conditions are met from a simple random sample of 30 observations, you obtain t = 2.35. Based on this result, describe the p-value. (4 points) Select one: a. The p-value falls between 0.15 and 0.2. b. The p-value falls between 0.025 and 0.05. c. The p-value falls between 0.01 and 0.02. d. The p-value falls between 0.005 and 0.01. e. The p-value is less than 0.005. 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. (4 points) Select one: a. 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. b. 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. c. 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. d. 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. e. 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.
