A researcher takes sample temperatures in Fahrenheit of 20 days from Portland (Group 1) and 19 days fromOklahoma City (Group 2). Test the claim that the mean temperature in Portland is different than the meantemperature in Oklahoma City. Use a significance level of a = 0.05. Assume the populations areapproximately normally distributed with unequal variances. You obtain the following two samples of data.Round answers to 4 decimal places.Portland Oklahoma City79.775.650.869.468.351.856.9505550.766.361.655.459.949.552.959.762.257.652.73964.866.370.2Test Statistic =p-value63.458.567.567What are the correct hypotheses?

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.
