Joven wants to estimate the average number of books people read in a year. He randomly selects 65 people from the US population and asks them to report how many books they read the previous year. The sample mean is 7.50 (M = 7.50). The standard deviation is 4.40 ( = 4.40). Calculate the 95% CI around this point estimate for average number of books people in the US read per year. Report in APA style. a) 95%CI [6.43, 8.57] c) 95%CI [6.95, 8.05] b) 95%CI [-1.12, 16.12] d) 95%CI [6.00, 9.00] 19
