Calculating Sample Statistics 2. Listed are head injury measurements from small cars that were tested in crashes. The measurements are in "hic," which is a measurement of a standard "head injury criterion," (lower "hic" values correspond to safer cars). Find the mean, variance, standard deviation, median, range, midrange, mode and coefficient of variation for the data. Round decimals to two places.

With a height of 65 inches, Ronald was the shortest president of a particular club in the past century. The club presidents of the past century have a mean height of 66.6 inches and a standard deviation of 2.4 inch. a) Compute the z score for Ronald's height. Round decimal to three places. b) Is Ronald's height usual or unusual? Explain. c) Use the club data to find the probability that the next club president will have a height taller than 69 inches.
