Do GA residents (population 1) spend more on cable than FL residents (population 2)? A GA sample of 100 showed an average bill of $120 with a standard deviation of $15. A FL sample of 100 showed an average bill of $110 with a standard deviation of $10. Formulate the hypothesis:

A. Ho: μ1–μ2<0 . Ha: μ1–μ2>0

B. Ho: μ1–μ2≤0 . Ha: μ1–μ2>0

C. Ho: μ1–μ2>0 . Ha: μ1–μ2≤ 0

D. Ho: μ1–μ2=0 . Ha: μ1–μ2>0

What is the p-value?

What is your conclusion at alpha = 0.05?

Obtain a 95% confidence interval for the difference between the two population means (GA = population 1, FL = population 2)

What is your conclusion based on the interval?
