The sample size is the number of people.

You can get the sample size by counting the completion times for each.

Sample size of men = 19

Sample size of women = 34

The mean time is the average time, so you need to add all the times for the men and divide it by the number of men and then the same for the women:

Mean time for men = 3129 / 19 = 164.68 seconds

Mean time for women = 5834 / 34 = 171.59 seconds.

The mean time taken by men is less than the women.

Answer:

Step-by-step explanation:

The Pythagorean triple (8, 15, 17) is often seen in algebra and geometry problems. You recognize it as choice A, so you know that is a right triangle.

A spreadsheet or graphing calculator can perform the tedium of comparing the sum of squares of the shorter sides to the square of the longer side. The attachment shows a spreadsheet used for that purpose. It identifies the triple (8, 15, 17) as the sides of a right triangle.
