It is known that the mean price of a college textbook was $85 in 2014 with the standard deviation of $16. Consider a random sample of 40 college textbooks marketed in 2014, and let X represent the mean of the sample. 17 Find the mean and standard deviation of X, i. e., X , X (Round off to two decimal places.) (a) 85, .4 (b) 13.44, 16 (c) 85, 2.53 (d) 85, 16 (e) 101, 2.53
