The air force reports that the distribution of heights of male pilots is approximately normal, with a mean of 72.6 inches and a standard deviation of 2.7
inches

Part A: A male pilot whose height is 74.2 inches is at what percentile? Mathematically explain your reasoning and justify your work.

Part B: Air force fighter jets can accommodate heights of soldiers between 70 inches and 78 inches without compromising safety. Anyone with a
height outside that interval cannot fly the fighter jets. Describe what this interval looks like if displayed visually. What percent of male pilots are unable
to fly according to this standard? Show your work and mathematically justify your reasoning.
