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. Class ​Frequency, f ​0-4 3 ​5-9 12 ​10-14 23 ​15-19 18 ​20-24 14 ​25-29 9 ​30+ 6
