A polling organization reported data from a survey of 2000
randomly selected Canadians who carry debit cards. Participants in
this survey were asked what they considered the minimum purchase
amount for which it would be acceptable to use a debit card.
Suppose that the sample mean and standard deviation were $9.11 and
$7.50, respectively. (These values are consistent with a histogram
of the sample data that appears in the report.)
Do these data provide convincing evidence that the mean minimum
purchase amount for which Canadians consider the use of a debit
card to be appropriate is less than $10? Carry out a hypothesis
test with a significance level of 0.01. (Use a statistical computer
package to calculate the P-value. Round your test
statistic to two decimal places and your P-value to three
decimal places.)

A report about how American college students manage their finances includes data from a survey of college students. Each person in a representative sample of 793 college students was asked if they had one or more credit cards and if so, whether they paid their balance in full each month.

In a smoking cessation program, over 2000 smokers who were trying to quit were randomly assigned to either a group program or an individual program. With no incentive, the proportion of smokers trying to quit who are still abstaining six months later is about 0.06. Participants in the study were randomly assigned to one of four different incentives, and the proportion successful was measured six months later. Of the 498 participants in the group with the least success, 47 were...
