In a survey of a group of men, the heights in the 20-29 age group were normally distributed, with a mean of 69.7 inches and a standard deviation of 4.0 inches. A study participant is randomly selected. Complete parts (a) through (d) below. (a) Find the probability that a study participant has a height that is less than 67 inches. (Round to four decimal places as needed.) The probability that the study participant selected at random is less than 67 inches tall is (b) Find the probability that a study participant has a height that is between 67 and 70 inches. The probability that the study participant selected at random is between 67 and 70 inches tall is (Round to four decimal places as needed.) (c) Find the probability that a study participant has a height that is more than 70 inches. (Round to four decimal places as needed.) The probability that the study participant selected at random is more than 70 inches tall is
