(Round to the nearest whole number as needed.)Engineers want to design seats in commercial aircraft so that they are wide enough to ft 90%% of all males. (Accommodating 100%% of males would require very wide seats that would be much too expensive.) Men have hip breadths that are normally distributed with a mean of 14.1 in. and a standard deviation of 0.9 in. Find Peg. That is, find the hip breadth for men that separates the smallest 90%% from the largest 10%%. The hip breadth for men that separates the smallest 90%% from the largest 10% is Pos = in.

A hospital uses 100.6'F as the lowest temperature considered to be a fever. What percentage of normal and healthy persons would be considered to have a fever? Does this percentage suggest that a cutoff of 100.6"F is appropriate? b. Physicians want to select a minimum temperature for requiring further medical tests. What should that temperature be, if we want only 5.0%% of healthy people to exceed it? (Such a result is a false positive, meaning that the test result is positive, but the subject is not really sick) Click to view page 1 of the table. Click to view page 2 of the table. a.
