Some candy bars include a voucher for a free movie. The candy company claims that a voucher
can be found in ten percent of candy bars. However, based on their experiences buying these
candy bars, a group of students believes that the proportion of candy bars with vouchers is less
than ten percent. To test the company’s claim, the students purchased 60 candy bars and found
a total of 3 vouchers. Use a 0.05 significance level to test the claim that the proportion of candy
bars with vouchers is less than ten percent.
