. Beatrice is graduating from college this semester and has received two job offers, one in city A and one in city B. To help her decide where to move, she would like to estimate the difference in average home prices for these two cities. From a random sample of 40 listings in city A the average home price is $190,000 and from a random sample of 40 listings in city B the average home price is $185,000. She finds that the margin of error for a 95% confidence interval for the difference in average home price between the two cities (A-B) is $3,250. Which of the following conclusions is correct? (A) Beatrice can be 95% confident that the average home price is between $1,750 and $8,250 more in city A than in city B. (B) Beatrice can be 95% confident that the average home price is between $1,750 and $8,250 less in city A than in city B. (C) Beatrice can be 95% confident that the average home price is $5,000 less in city A than in city B. (D) Beatrice can be 95% confident that the average home price is $5,000 more in city A than in city B. (E) Beatrice can be 95% confident that there is not a significant difference in the average home price between these two cities.
