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. Theresults are listed below. Construct a 99% confidence interval estimate of the mean. What is the practical use of theconfidence interval?2, 2, 1, 3, 4, 3, 4, 4, 3, 1What is the confidence interval for the population mean µ?|<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 theanswer boxes to complete your choice.O A. The confidence interval can be used to estimate that, with 99% confidence, the interval from toactually contains the true mean DNA base of all people.(Round to one decimal place as needed.)B. The given numbers are just substitutes for the four DNA base names, so the numbers do not measure orcount anything, and they are at the nominal level of measurement. The confidence interval has no practicaluse.C. The confidence interval can be used to estimate that 99% of all people have DNA bases between0.(Round to one decimal place as needed.)and

It is assumed that µ is the population mean of DNA bases.

Choose the appropriate statistical test. When computing, be sure to round each answer as indicated. A dentist wonders if depression affects ratings of tooth pain. In the general population, using a scale of 1-10 with higher values indicating more pain, the average pain rating for patients with toothaches is 6.8.
