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. Atlanta New Orleans 793.5 799 800.4 813.5 773.8 788.3 792.4 780.8 773.1 793.5 804.8 809.2 807.6 803.6 814.8 824.3 811.8 802.9 788.1 816.5 800.6 789.7 791.4 What are the correct hypotheses? Note this may view better in full screen mode. Select the correct symbols for each of the 6 spaces. Ho: P H₁: ₁ Based on the hypotheses, find the following: Test Statistic = -2.5904 X p-value = 0.0087 X H₂ The p-value is less than (or equal to) alpha H₂ oto alpha.
