In the picture below, I have the output for the same two sets of data. I ran the hypothesis test and the confidence interval. If you had a choice to use one output or the other, which would you choose and why? Make sure to be specific and include what information you get from each and what information you don't get if you use one over the other. Options Two sample T summary hypothesis test: : Mean of Population 1...

All of the following are TRUE about 95% confidence intervals for a population mean except ::* O a. The population mean may or may not be in the confidence interval. Ob. The value of T varies depending on sample size. Oc. If the sample size is large, the Central Limit Theorem says...
Use the t-distribution to find a confidence interval for a mean u given the relevant sample results. Give the best point estimate for u, the margin of error, and the confidence interval. Assume the results come from a random sample from a population that is approximately normally distributed. A 95% confidence interval for u using the sample results I = 10.5,5 = 6.9, and n = 30 Round your answer for the point estimate to one decimal place, and your...
Use the given degree of confidence and sample data to construct a confidence interval for the population mean H. Assume that the population has a normal distribution. Thirty randomly selected students took the calculus final. If the sample mean was 82 and the standard deviation was 12.6, construct a 99% confidence interval for the mean score of all students. Round to two decimal places. O A. 75.68 < < 88.32 OB. 75.66<u < 88.34 OC. 78.09 < < 85.91 OD....
