The estimated distribution (in millions) of the population by age in a certain country for the year 2015 is shown in the pie chart. 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. Use 70 as the midpoint for "65 years and over." Under 4 years: 19.7 5-14 years: 47.1 15-19 years: 19.4 20-24 years: 20.2 The sample mean is x=(Round to two decimal places as needed.) 25-34 years: 49.7 35-44 years: 43.6 45-64 years: 88.1 65 years and over: 53.2
