Statistics Canada divides families into two groups: couple families and lone-parent families. According to Statistics Canada’s Table 1110009 “Family Characteristics, Summary,” in 2012 in Nova Scotia, the data were as follows:

A surveyor calls 1000 families in Nova Scotia at random in order to market products of different types to the two types of family. For each of the following questions, either answer the question or state why it is not possible to answer it with the information provided and the methods given in this chapter. Give answers to four significant figures.

a) What is the expected proportion of lone-parent families in this sample?

b) What is the probability that the proportion of loneparent families in the sample will be greater than 0.19?

c) What is the expected average number of people per couple family in the sample?

d) What is the probability that the average number of people per couple family is less than 2.5?

e) What is the expected median total income of couple families in the sample?

f) What is the probability that the median total income of lone-parent families in the sample is less than $30,000?
