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 Ffor the data. Then use the table to estimate the sample mean and the sample standard deviation of the data set. A Click the icon to view the pie chart.
