A researcher takes sample temperatures in Fahrenheit of 18 days from Pittsburgh and 16 days from Cleveland. Use the sample data shown in the table. Test the claim that the mean temperature in Pittsburgh greater than the mean temperature in Cleveland. Use a significance level of a = 0.01. 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.

Question
Transcribed Image Text:A researcher takes sample temperatures in Fahrenheit of 18 days from Pittsburgh and 16 days from
Cleveland. Use the sample data shown in the table.
Test the claim that the mean temperature in Pittsburgh greater than the mean temperature in Cleveland.
Use a significance level of a = 0.01.
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.
