The distribution of the number of hours that a random sample of people spend doing chores per week is shown in the pie chart. Use 32 as the midpoint for "30+ hours." Make a frequency distribution for the data. Then use the table to estimate the sample mean and the sample standard deviation of the data set

0-4 hours; 4 people

5-9 hours,9 people

10-14 hours:22 people

15-19 hour,21 people

20-24hour,15 people

25-29hour,14 people

30+hours,5 people

First construct the frequency distribution.
