The American Research Group, Inc. conducted a telephone survey
of a random sample of 1,100 U.S. adults in a recent year and
determined that the average amount of planned spending on gifts for
the holiday season was $854 and that 40% of the purchases would be
made from catalogs. Shown below are the average amounts of planned
spending on gifts for the holiday season for 11 years along with
the associated percentages to be made from catalogs.
Year Average Percentage Purchases Spending ($) to Be Made from Catalogs 1 1,037 44 2 976 42 3 1,004 47 4 942 47 5 907 50 6 859 51 7 431 43 8 co 417 36 9. 658 26 10 646 42 11 854 40 Develop a regression model to predict the number of rentals per day by the average family income. Comment on the output. For a = .01 the value of the test statistic is t = , so the decision is the null hypothesis. (Do not round the intermediate values. Round the answer to 2 decimal places.)
