An article about the California lottery gave the following information on the age distribution of adults in California: 35% are between 18 and 34 years old, 51% are between 35 and 64 years old, and 14% are 65 years old or older. The article also gave information on the age distribution of those who purchase lottery tickets. The following table is consistent with the values given in the article. Suppose that the data resulted from a random sample of 200...

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: 21.5 5-14 years: 39.9 15-19 years: 20.3 20-24 years: 22.3 25-34 years: 48.4 35-44 years: 37.8 45-64 years:...
