Choose a person aged 19 to 25 years at random and ask, "In the past seven days, how many times did you go to an exercise or fitness center or workout?" Let Y be the number of days worked out. Below is the probability distribution of Y. Fill in the chart.

What is the mean number of days worked out?

Calculate and interpret the standard deviation of Y.

The mean is 1.03. The standard deviation is 1.76 and the variance is 3.12. For the days you worked out, your score typically varies 1.76 from the mean of 1.03.
