A common measure of flexibility is the sit-and-reach test, where a person sits on the floor with legs straight in front. The person then reaches as far forward as possible, and the distance reached past the feet is recorded. The histograms summarize the results of the sit-and-reach test for two groups, young adult men and middle-aged men. Negative distances represent a reach that is not as far as the feet.

The distribution for young adult men is approximately symmetric, and the distribution for middle-aged men is skewed to the right. The distribution for young adult men is approximately symmetric, and the distribution for middle-aged men is skewed to the left. The distribution for young adult men is skewed to the right, and the distribution for middle-aged men is approximately symmetric. The distribution for young adult men is skewed to the left, and the distribution for middle-aged men is approximately symmetric.

Question
Transcribed Image Text:A common measure of flexibility is the sit-and-reach test, where a person sits on the floor with legs straight in front.
The person then reaches as far forward as possible, and the distance reached past the feet is recorded. The
histograms summarize the results of the sit-and-reach test for two groups, young adult men and middle-aged men.
Negative distances represent a reach that is not as far as the feet.
