Chapter 7, Problem 19PS

The topic of global warming increasingly appears in the news. It has the potential to impact companies’ operations through changes in governmental regulations, new reporting requirements, necessary operational changes, and so on. The institute of Management Account (IMA) conducted a survey of senior finance professionals to gauge members’ thoughts on global warning and its impact on their companies. The survey found that 65 % of senior finance professionals believe that global warming is having a significant impact on the environment.

Suppose that you select a sample of 100 senior finance professionals.

a. What is the probability that the sample percentage indicating global warming is having a significant impact on the environment will be between 64 % and 69 % ?

b. The probability is 90 % that the sample percentage will be contained within what symmetrical limits of the population percentage?

c. The probability is 95 % that the sample percentage will be contained within what symmetrical limits of the population percentage?

d. Suppose you selected a sample of 400 senior finance professionals. How does this change your answer in (a) through (c)?
