Please complete steps C and D. Thank you. d. Construct a 95% prediction interval for the amount spent by a customer who purchases 5 PFC drinks per week. UPL = LPL = Opinions are split about a coffee company's pumpkin-flavored coffee (PFC). Yet every year over the last five years, the consumption of pumpkin-flavored goods has increased. If we look at the numbers, it also becomes clear why a leading coffee company keeps offering the PFC earlier and earlier every year. According to a magazine, the amount spent by PFC buyers at the coffee company is about 17% higher than non-PFC buyers. The accompanying table shows a random sample of eight consumers, the amount they spend per week, and the number of PFCs purchased per week. The regression line for the data is y = 5.6983 + 4.3651x, and the SSE of the regression is 112.466. Use this information to complete parts a through d. Click the icon to view the number of pumpkin-flavored coffees purchased and the total amount spent for 8 consumers. Table of PFC and Spending PFC: 2 8 4 1 3 2 6 2 Spending: 13.19 38.53 19.52 9.24 15.22 21.27 37.53 13.31 a. Calculate the coefficient of determination. R^2 = 0.871 (Round to three decimal places as needed.) b. Using α = 0.05, test the significance of the population coefficient of determination. Determine the null and alternative hypotheses. H0: β2 = 0 Ha: β2 > 0 The F-test statistic is 40.66 (Round to two decimal places as needed.) The p-value is 0.001 (Round to three decimal places as needed.) Because the p-value is less than 0.05, reject the null hypothesis. There is enough evidence to conclude that the coefficient of determination is significant. c. Construct a 95% confidence interval for the average amount spent by a customer who purchases 5 PFC drinks per week. UCL = dollars LCL = dollars
