A new roller coaster at an amusement park requires individuals to be at least 4' 8" (56 inches) tall to ride. It is estimated that the heights of 10-year-old boys are normally distributed with mu equals 53.5 inches and sigma equals 5 inches. a. What proportion of 10-year-old boys is tall enough to ride the coaster? b. A smaller coaster has a height requirement of 50 inches to ride. What proportion of 10-year-old boys is tall enough to ride this coaster? c. What proportion of 10-year-old boys is tall enough to ride the coaster in part b but not tall enough to ride the coaster in part a? a. The proportion of 10-year-old boys tall enough to ride the coaster is 0.3085. (Round to four decimal places as needed.) b. The proportion of 10 year-old-boys tall enough to ride the smaller coaster is 0.7580. (Round to four decimal places as needed.) c. The proportion of 10-year-old boys tall enough to ride the coaster in part b but not tall enough to ride the coaster in part a is nothing. (Round to four decimal places as needed.)
