↓ Samples of DNA are collected, and the four DNA bases of A, G, C, and T are coded as 1, 2, 3, and 4, respectively. The results are listed below. Construct a 99% confidence interval estimate of the mean. What is the practical use of the confidence interval? 1, 1, 2, 3, 4, 3, 4, 4, 3, 2 What is the confidence interval for the population mean μ? << (Round to one decimal place as needed.) What is the practical use of the confidence interval? Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. OA. The confidence interval can be used to estimate that, with 99% confidence, the interval from (Round to one decimal place as needed.) to actually contains the true mean DNA base of all people. OB. The confidence interval can be used to estimate that 99% of all people have DNA bases between (Round to one decimal place as needed.) and OC. The given numbers are just substitutes for the four DNA base names, so the numbers do not measure or count anything, and they are at the nominal level of measurement. The confidence interval has n practical use. A data set includes data from student evaluations of courses. The summary statistics are n = 93, x=3.83, s = 0.68. Use a 0.10 significance level to test the claim that the population of student course evaluations has a mean equal to 4.00. Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. What are the null and alternative hypotheses? OA. Ho μ*4.00 H₁ =4.00 OC. Ho p=4.00 H₁:p>4.00 Determine the test statistic. (Round to two decimal places as needed.) Determine the P-value. ☐ (Round to three decimal places as needed.) State the final conclusion that addresses the original claim. Ho. There is OB. Ho H=4.00 H₁ #4.00 OD. Ho p=4.00 Η μ < 4.00 evidence to conclude that the mean of the population of student course evaluations is equal to 4.00 correct.
