O An exponential model is appropriate because the residual plot does not show a clear pattern. O A inear model is appropriate because the scatterplot shows a strong, positive linear relationship. A power model is appropriate…
Applying the Concepts and SkillsStudy Time and Score. An instructor at Arizona State University asked a random sample of eight students to record their study times in a beginning calculus course. She then made a table for total hours studied (x) over 2 weeks and test score (y) at the end of the 2 weeks. Here are the results. x 10 15 12 20 8 16 14 22 y 92 81 84 74 85 80 84 80 Study Time and Score. Following are the data on total hours studied over 2 weeks and test score at the end of the 2 weeks from Exercise 15.27. x 10 15 12 20 8 16 14 22 y 92 81 84 74 85 80 84 80 a. At the 1% significance level, do the data provide sufficient evidence to conclude that a negative linear correlation exists between study time and test score for beginning calculus students?b. Repeat part (a) using a 5% significance level.
YG SHORT ANSWER. Write the word or phrase that best completes each statement or answers the question. 1) A local company is concerned about the number of days missed by its employees due to illness. A random sample of 10 employees is selected. The number of days absent in one year is listed below. An incentive program is offered in an attempt to decrease the number of days absent. The number of days absent in one year after the incentive program is listed below. Test the claim that the incentive program cuts down on the number of days missed by employees. Use a = 0.05. Assume that the distribution is normally distributed. Employee Days absent before 3 incentive E | F|G| H ||| J 9 4 2 B Days absent after incentive 2
FIND THE ANSWERS FOR B-2 and C. A survey found that Massachusetts residents spent an average of $861.75 on the lottery, more than three times the U.S. average. A researcher at a Boston think tank believes that Massachusetts residents spend less than this amount. He surveys 100 Massachusetts residents and asks them about their annual expenditures on the lottery. (You may find it useful to reference the t table.) Click here for the Excel Data File a.
