Question
An agent for a real estate company in a suburb has the business objective of developing more accurate estimates of the monthly rental cost for apartments. The agent would like to use the size of an apartment, as defined by square footage to predict the monthly rental cost. The agent collects data from a sample of 30 one-bedroom apartments. Complete parts (a) through (c). Click the icon to view the data table. a. Construct a 95% confidence interval estimate of the mean monthly rental for all one-bedroom apartments that are 820 square feet in size. OSHYIX = 820 (Type integers or decimals. Round to two decimal places as needed. Use ascending order.) b. Construct a 95% prediction interval of the monthly rental for an individual one-bedroom apartment that is 820 square feet in size. Data table OsYx= 820 U (Type integers or decimals. Round to two decimal places as needed. Use ascending order.) Apartment Size (sq feet) Rent ($) c. Explain the differences in the results from (a) and (b). 1 534 1102 O A. Since there is more variation in predicting an individual value than in estimating a mean value, the prediction interval is narrower than the confidence interval, holding everything else fixed. 624 1170 3 657 1192 O B. Since there is more variation in estimating a mean value than in predicting an individual value, the confidence interval is narrower than the prediction interval, holding everything else fixed. 4 836 1412 O C. Since there is more variation in estimating a mean value than in predicting an individual value, the confidence interval is wider than the prediction interval, holding everything else fixed. 450 1203 6. 542 1233 O D. Since there is more variation in predicting an individual value than in estimating a mean value, the prediction interval is wider than the confidence interval, holding everything else fixed. 7 786 1467 8. 807 1500 9. 1073 1511 10 619 1675 11 823 1821 12 662 1643 13 597 1453 14 680 1387 15 736 1144 16 829 1149 17 912 1233 18 618 1435 19 649 1529 20 827 1099 21 789 1123 22 793 1254 23 932 1449 24 785 1160 25 788 1225 26 969 1390 27 738 1143 28 677 1083 29 825 1344 30 862 1518
