Consider the following hypothesis test: H0: μ = 15, Ha: μ ≠ 15. A sample of 50 provided a sample mean of 14.15. The population standard deviation is 3. Compute the confidence interval at the 95% level. Based on the interval you calculated, what is your conclusion regarding the two hypotheses? Confidence interval: Conclusion: Check

The following hypothesis test is to be conducted. H0: Median ≤ 150 H1: Median > 150 A sample of 30 provided 22 observations greater than 150, 3 observations equal to 150, and 5 observations less than 150. Use α = .01. What is your conclusion?

Consider the following hypothesis test: H0: µ = 50 and Ha: µ > 50. A sample of 60 provided a sample mean of 51.8. The population standard deviation is 8 and the test level of significance is set at α = .05. You compute the critical value for this test statistic. You compute the value of the test statistic and find it is equal to? Based on the critical value approach, your conclusion is to reject or not H0?
