Engineers must consider the diameters of heads when designing helmets. The company researchers have determined that the population of potential clientele have head diameters that are normally distributed with a mean of 6.4-in and a standard deviation of 0.9-in. Due to financial constraints, the helmets will be designed to fit all men except those with head diameters that are in the smallest 1.1% or largest 1.1%.
