Question

The following figure is a Normal probability plot of the heart rates of 200 male runners after 6 minutes of exercise on a treadmill.

What is the shape of the distribution of heart rates?

- It cannot be determined from the Normal probability plot.
- Approximately Normal
- Symmetric with two peaks.
- Skewed right
- Skewed left

Answer 1

Approximately Normal

Explanation:

From a Normal probability plot, you can assess whether the data follows a normal distribution or not. A Normal probability plot typically displays data points along a straight line if they are normally distributed.

If the data points in the plot form a straight line, it indicates that the data is approximately normally distributed. In this case, the shape of the distribution of heart rates would be "Approximately Normal."

So, the correct answer is "Approximately Normal."
