A sample of 10 different parts are tested using a low temperature level and another sample of 10parts is also tested using a high temperature level. The random variable of interest is theshrinkage that occurred in the units, measured in percentage. Assume that the data sets followthe normal distribution. The results are as follows:Low Temperature High Temperature21.217.917.620.918.315.916.519.820.320.517.821.316.118.720.819.716.421.517.220.3s = 0.9709a) Compare the variances of the temperatures using a hypothesis test with a significance level of0.02. Set up the appropriate hypotheses test to check if there is a difference between thevariances.b) Compute a 98% two-sided confidence interval on the appropriate parameter to check if thereis a difference between the variances.c) Does temperature have an effect on shrinkage? Perform a hypothesis test to prove if there isany difference in the mean shrinkage, considering the conclusion from part a). Use a significancelevel of 0.02

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.

Listed below are systolic blood pressure measurements (mm Hg) taken from the right and left arms of the same woman. Assume that the paired sample data is a simple random sample and that the differences have a distribution that is approximately normal. Use a 0.01 significance level to test for a difference between the measurements from the two arms. What can be concluded? Right arm 147 151 120 132 138 Left arm 177 166 173 145 149 In this example, μd is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the measurement from the right arm minus the measurement from the left arm. What are the null and alternative hypotheses for the hypothesis test? Identify the test statistic. t= (Round to two decimal places as needed.)
