I am having trouble setting up this problems. While answers are welcome, I am interested in figuring out how to read the word problem and plug in the information to arrive at the answer. Please look at the attached document.

2 2. A family wants to move to a new city. They are deciding between two cities in different areas of the country: Avalon and Boyton. Income levels for the two cities were compared to see if incomes differed between the two residential areas. The sample means, standard deviations and sample sizes are provided below. Construct a 95% confidence interval for the difference in income between the two cities. Interpret the confidence interval. Avalon: X,= $50, 000 S1 = $15,000 n1 = 40 Boyton: X2= $65,000 $2 = $20,000 n2 = 36
