CR10.6 The article “Should Canada Allow Direct-to-Consumer Advertising of Prescription Drugs?” (Canadian Family Physician

[2009]: 130–131) calls for the legalization of advertising of prescription drugs in Canada. Suppose you wanted to conduct a survey to estimate the proportion of Canadians who would support allowing this type of advertising. How large a random sample would be required to estimate this proportion to within .02 with 95% confidence?

CR10.7 The National Association of Colleges and Employers carries out a student survey each year. A summary of data from the 2009 survey included the following information:

• 26% of students graduating in 2009 intended to go on to graduate or professional school.

• Only 40% of those who graduated in 2009 received at least one job offer prior to graduation.

• Of those who received a job offer, only 45% had accepted an offer by the time they graduated.

Consider the following events:

O 5 event that a randomly selected 2009 graduate received at least one job offer A 5 event that a randomly selected 2009 graduate accepted a job offer prior to graduation G 5 event that a randomly selected 2009 graduate plans to attend graduate or professional school Compute the following probabilities.

a. P(O)

b. P(A)

c. P(G)

d. P(AuO)

e. P(OuA)

f. P(A > O)
