A researcher takes sample temperatures in Fahrenheit of 20 days from Hartford and 18 days from Denver Use the sample data shown in the table. Test the claim that the mean temperature in Hartford is different than the mean temperature in Denver Use a significance level of o 0.10. Assume the populations are approximately normally distributed with unequal variances. Note that list 1 is longer than list 2, so these are 2 independent samples, not matched pairs.
