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 5.6-in and a standard deviation of 0.8-in. Due to financial constraints, the helmets will be designed to fit all men except those with head breadths that are in the smallest 1.9% or largest 1.9%. What is the minimum head breadth that will fit the clientele? min = What is the maximum head breadth that will fit the clientele? max = Enter your answer as a number accurate to 1 decimal place. Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted.
for 1.9th percentile critical value of z= | -2.075 | ||
therefore corresponding minimum head breadth=mean+z*std deviation= | 3.9 |
for 98.1th percentile critical value of z= | 2.075 | ||
therefore corresponding maximum head breadth=mean+z*std deviation= | 7.3 |
