A researcher is studying how much electricity (in kilowatt hours) people from two different cities use in their homes. Random samples of 11 days from Atlanta (Group 1) and 12 days from New Orleans (Group 2) are shown below. Test the claim that the mean number of kilowatt hours in Atlanta is less than the mean number of kilowatt hours in New Orleans. Use a significance level of a = 0.05. Assume the populations are approximately normally distributed with unequal variances. Round answers to 4 decimal places.

Transcribed Image Text:A researcher is studying how much electricity (in kilowatt hours) people from two different cities use in
their homes. Random samples of 11 days from Atlanta (Group 1) and 12 days from New Orleans (Group 2)
