Question

for men of 80 years of age and older, a weight of 233.5 pounds falls on the 95th percentile. what percentage of men of 80 years of age or older will weigh more than 233.5 pounds?

Explanation:

Step1: Understand the concept of percentile

The \(p\)th percentile of a data set is a value such that \(p\%\) of the data values are less than or equal to this value.

Step2: Calculate the percentage of men weighing more

If a weight of \(233.5\) pounds is the \(95\)th percentile, then \(95\%\) of men are of weight less than or equal to \(233.5\) pounds.
The percentage of men weighing more than \(233.5\) pounds is \(100\% - 95\%=5\%\)

Answer:

\(5\%\)
