# Compute the relative frequency and cumulative relative frequency

CAN YOU DO:I HAVE EBOOKData from the 2000 U.S. Census show the following distribution of ages for residents of Ohio:  Total Households  4,445,773   Family households (families)  2,993,023   With own children under 18 years  1,409,912   Married‐couple family  2,285,798   With own children under 18 years  996,042   Female householder, no husband present  536,878   With own children under 18 years  323,095   Nonfamily households  1,452,750   Householder living alone  1,215,614   Householder 65 years and over  446,396  a.  Construct a column chart to visually represent these data.  b.  Construct a stacked bar chart to display the sub categories where relevant. (Note that you will have to compute additional subcategories, for instance, under Family households, the number of families without children under 18, so that the total of the subcategories equals the major category total. The sum of all categories does not equal the total.)   c.  Construct a pie chart showing the proportion of households in each category.   A community health status survey obtained the following demographic information from the respondents:       Age  Frequency   18–29  297   30–45  661   46–64  634   65 +  369   Compute the relative frequency and cumulative relative frequency of the age groups. Also, estimate the average age of the sample of respondents. What assumptions do you have to make to do this?
