The Young Children’s Charity of Eastern Canada would like to provide an accurate estimate of how much it costs to raise a child between the ages of 2 and 12 each year for its fundraising campaign. The organization hired you to find out how much households spent on raising a child in 2006 for clothing, toys/recreation, education, babysitting, and a percentage of the expenses for family food, utilities (electricity and gas), transportation, and rent or house payments. The charity gave you a list of four million residential telephone customers in the area it will operate the campaign. You sampled every four-thousandth address on the list. The charity will have a professional survey company contact each sampled household by telephone and ask whether or not there is a child between 2 and 12 years old living in the household. If there is, the interviewers will ask other questions and record the total amount spent raising a child in the past two months. They will multiply this amount by 6 to get an annual cost. 12) Lucy Lively, a coffee aficionado, wanted to draw a sample of people in Ontario who own an authentic, imported Italian espresso coffee maker.
