Chapter 4, Problem 11PE

A marketing study of 800 adults in the 18—34 age group reported the following information:

• spent less than $100 but more than $0 on children’s clothing per year: 50 responses

• spent $100-$499.99 on children’s clothing per year; 275 responses

• spent $500—$999.99 on children’s clothing per year; 175 responses

• spent nothing the remainder

Develop a spreadsheet to estimate the sample mean and sample standard deviation of spending on children’s clothing for this age group using formulas (4.14) and (4.16).
