A researcher takes sample temperatures in Fahrenheit of 15 days from Las Vegas (Group 1) and 25 days from Memphis (Group 2). Test the claim that the mean temperature in Las Vegas is different than the mean temperature in Memphis. Use a significance level of o = 0.01. Assume the populations are approximately normally distributed with unequal variances. You obtain the following two samples of data. Round answers to 4 decimal places. Las Vegas Memphis 75.4 78.6 86.7 68.7 105.6 73.4 55.1 84.8 86.3 77.6 55.1 71.7 84.8 92.2 52.5 85.9 60.4 71.4 90.7 70.9 87.7 75.2 134.6 76.8 52.5 90.493.6 65.3 107 81.4 78.3 80.1 65.3 75.3 73.6 80.5 77.8 69.1 76.3 81.6 That are the correct hypotheses?
