Answer:
37th percentile.
Step-by-step explanation:
We have been given a data set that represents the ages of 36 executives. We are asked to find the percentile that corresponds to an age of 41 years.
28, 29, 29, 32, 32, 33, 34, 34, 34, 34, 37, 37, 38, 41, 41, 42, 45, 45, 47, 47, 47, 48, 50, 51, 53, 56, 56, 56, 61, 61, 62, 63, 64, 64, 65, 66.
Let us count the number of data points below and at 41.

We will use percentile formula to solve our given problem.
Therefore, the percentile rank that corresponds to age of 41 years old is 37th percentile.
