Question

A study of the ability of individuals to walk in a straight line reported the accompanying data on cadence (strides per second) for a sample of n = 20 randomly selected healthy men. What is the cadence (strides per second) for the sample of healthy men?

Answer 1

The cadence (strides per second) for the sample of healthy men can be found by calculating the average of the given data.

Step-by-step explanation:

The cadence (strides per second) for the sample of healthy men can be found by calculating the average of the given data. First, add up all the cadence values, and then divide the sum by the number of values in the sample.

Let's say the cadence values are:

2, 3, 4, 2, 3, 5, 4, 3, 3, 1, 2, 4, 2, 3, 3, 4, 2, 3, 4, 5

Adding them up: 2 + 3 + 4 + 2 + 3 + 5 + 4 + 3 + 3 + 1 + 2 + 4 + 2 + 3 + 3 + 4 + 2 + 3 + 4 + 5 = 65

Now divide the sum by the number of values in the sample:

65 / 20 = 3.25

Therefore, the cadence for the sample of healthy men is 3.25 strides per second.
