Engineers must consider the breadths of male heads when designing helmets. The company researchers have determined that the population of potential clientele have head breadths 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 breadths that are in the smallest 3.4% or largest 3.4%.

What is the minimum head breadth that will fit the clientele? min = What is the maximum head breadth that will fit the clientele? max =
