The distribution of heights of adult men in the U.S. is approximately normal with mean 69 inches and standard deviation 2.5 inches. Use what you know about a normal distribution and the 68-95-99.7 rule to answer the questions in parts (a), (b), (c) below. Your answer must be entered in the correct format. If your answer is a percent, such as 25 percent, enter: "25 PERCENT" (without the quotes). If your answer is in inches, such as 10 inches, enter: "10 INCHES" (without the quotes and with a space between the number and the INCHES). If your answer is an interval, such as 14 to 15 inches, then enter: "14 TO 15 INCHES" (without the quotes). Don't report accuracy greater than what comes from the 68-95-99.7 rule! For example, if the rule says "10 INCHES" then "10.0 INCHES" is wrong because the extra decimal place claims too much accuracy. If the rule says "1.2 INCHES" then "1.20 INCHES" is wrong. (a) Between what approximate heights do the middle 95 percent of men fall? Answer: (b) About what percent of men are shorter than 66.5 inches? Answer: (c) About what percent of men are taller than 69 inches? Answer:
