A researcher takes sample temperatures in Fahrenheit of 16 days from San Francisco (Group 1) and 22 days from Atlanta (Group 2). Test the claim that the mean temperature in San Francisco is less than the mean temperature in Atlanta. Use a significance level of a = 0.10. Assume the populations are approximately normally distributed with unequal variances. You obtain the following two samples of data. Round answers to 4 decimal places. San Francisco 77.4 94.8 77 80.9 84 73.4 84.9 92 60.6 83.6 92.5 76.3 93.4 87.2 81.5 70.4 Test Statistic = Atlanta 85.4 92.8 80.2 87.9 80.6 77.9 p-value = 72.9 75.9 72.1 76.7 80.4 What are the correct hypotheses?
