Question

Although airline schedules and cost are important factors for business travelers when choosing an airline carrier, a uSa today survey found that business travelers list an airline’s

frequent flyer program as the most important factor. From a sample of n = 1993 business

travelers who responded to the survey, 618 listed a frequent flyer program as the most important factor.

a. What is the point estimate of the proportion of the population of business travelers

who believe a frequent flyer program is the most important factor when choosing an

airline carrier?

b. Develop a 95% confidence interval estimate of the population proportion.

c. How large a sample would be required to report the margin of error of .01 at 95%

of precision? Why or why not?
