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. The p-value falls between 0.15 and 0.2. The p-value falls between 0.025 and 0.05. The p-value falls between 0.01 and 0.02. The p-value falls between 0.005 and 0.01. The p-value is less than 0.005.

Consider testing H0: mu = 45 vs. H1: mu <> 45 at the alpha = 0.01 level of significance ('<>' means 'not equal'). A sample of size n = 50 is taken and a 99% confidence interval for mu is calculated as (33.4, 44.7). Then the test conclusion is: Reject H0 Do not reject H0 There is not enough information to determine the test conclusion
