A country club wants to exam the effects of a new marketing campaign that attempts to get more people within the community to become members. In many communities, when people buy a house in the area, they receive a “Welcome Wagon” gift basket containing coupons to local restaurants. The idea of the marketing campaign is to include a free two month membership to the country club in the gift basket with the hope that once “new” residents try the country club then at least a certain proportion will want to become real members. One member of the Club’s Executive Council believes that at least 79% of the people who receive the coupons for the free membership will use the coupon. In a sample of 196 new residents who received the coupon for the two month free membership, there were 142 people who actually took advantage of the free two month membership. When testing the hypothesis that at least 79% of the people that receive the coupon actually use it, what is the test statistic?

- A survey by the Arthur Andersen Enterprise attempted to determine what the leading challenges are for the growth and survival of small businesses. Although the economy and finding qualified workers were the leading challenges, several others were listed in the results of the study, including regulations, listed by 30% of the companies, and the tax burden, listed by 35%. Suppose that 71% of the companies listing regulations as a challenge also listed the tax burden as a challenge. Assume these percentages hold for all small businesses. 1. If a small business is randomly selected, find the following probabilities: (a) The small business lists either the tax burden or regulations as a challenge. (b) The small business lists either the tax burden or regulations but not both as a challenge. (c) The small business does not list regulations as a challenge given that it lists the tax burden as a challenge. (d) The small business does not list regulations as a challenge given that it does not…arrow_forwardMany investors and financial analysts believe the Dow Jones Industrial Average (DJIA) gives a good barometer of the overall stock market.
