An article in Technometrics (1999, Vol. 41, pp. 202-211) studied the capability of a gauge by measuring the weight of paper. The datafor repeated measurements of one sheet of paper are in the following table. Construct a 90% one-sided, upper confidence interval forthe standard deviation of these measurements. Assume population is approximately normally distributed.Round your answer to 3 decimal places.Observations3.4813.4773.470os3.4483.4723.4703.4853.4643.4773.4753.4723.4733.4723.4703.474

Question 2 A researcher is interested in finding a 98% confidence interval for the mean number minutes students are concentrating on their professor during a one hour statistics lecture. The study included 149 students who averaged 37.9 minutes concentrating on their professor during the hour lecture. The standard deviation was 10.6 minutes. Round answers to 3 decimal places where possible. a. To compute the confidence interval use a? distribution. b. With 98% confidence the population mean minutes of concentration is between minutes. c. If many groups of 149 randomly selected members are studied, then a different confidence interval would be produced from each group. About percent of these confidence intervals will contain the true population mean minutes of concentration and about percent will not contain the true population mean minutes of concentration.

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. A sample of 30 patients that show high levels of depression have an average pain rating of 7.1 (variance 0.8). What should the dentist determine? 1. Calculate the estimated standard error. (round to 3 decimals). [st.error] 2. What is thet-obtained? (round to 3 decimals). 3. What is the t-cv? (exact value) 4. What is your conclusion? Only type "Reject" or Retain"
