A researcher takes sample temperatures in Fahrenheit of 20 days from Portland (Group 1) and 19 days from Oklahoma City (Group 2). Test the claim that the mean temperature in Portland is different than the mean temperature in Oklahoma City. Use a significance level of a = 0.05. Assume the populations are approximately normally distributed with unequal variances. You obtain the following two samples of data. Round answers to 4 decimal places. Portland 68.3 51.8 56.9 p-value 50 55 50.7 66.3 61.6 55.4 59.9 49.5 52.9 59.7 62.2 57.6 52.7 39 64.8 66.3 70.2 What are the correct hypotheses? Note this may view better in full screen mode. Select the correct symbols for each of the 6 spaces. Ho: Select an answer ? Select an answer H₁: Select an answer ?
