QUESTION 5 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 80% of the people who receive the coupons for the free membership will use the coupon. In a sample of 197 new residents who received the coupon for the two month free membership, there were 136 people who actually took advantage of the free two month membership. When testing the hypothesis that at least 80% of the people that receive the coupon actually use it, what is the test statistic?…
QUESTION 1 Smokers at a company were invited to participate in a smoking cessation program, and were randomly assigned to one of two groups. Those in the Reward group would get a cash award if they stopped smoking for 6 months. Those in the Deposit group were asked to deposit some money which they would get back along with a substantial bonus if they stopped smoking for 6 months. After six months, 156 of the 914 smokers who accepted the invitation to be in the reward-only program stopped smoking, while 78 of the 146 smokers who paid a deposit quit. A two-way table for this data is given below. (Be careful: "Total" rows/columns are not included.) Quit Smoking Yes No Treatment Group Reward 156 758 Deposit 78 68 Use this table to answer Problems 1-4. 1) How many people in the study had quit smoking after six months? Calculate the difference in proportion who quit smoking, , between those in the Deposit program and those…

Question 4a. A large accountancy firm finds that over the long run 10% of its statements for clients are in error in some way. A quality assurance officer at the firm investigating the source of the errors takes a sample of 20 statements produced by a single employee and classifies each as being “in error” or “not in error”.i. If the variable X is used to represent the number of statements in the sample that are in error, and assuming the error rate is the firm’s level of 10% then state:• the type of distribution this variable has; and• the parameter/s of this distribution. ii. Determine the probability that 2 or less returns in this sample are in error. The quality assurance officer found that there were 5 statements in the sample that were in error.iii. Determine the probability of finding 5 or more returns in error if indeed the error rate was 10%. iv. Based upon your answer for part iii., what conclusion might the quality assurance office make about this employee in terms of the…
Question 2 The past records of a supermarket show that its customers spend an average of $65 per visit at this store. Recently the management of the store initiated a promotional campaign according to which each customer receives points based on the total money spent at the store, and these points can be used to buy products at the store. The management expects that as a result of this campaign, the customers should be encouraged to spend more money at the store. To check whether this is true, the manager of the store took a sample of 12 customers who visited the store. The following data give the money (in dollars) spent by these customers at this supermarket during their visits. 88 69 141 28 106 45 32 51 78 54 110 83 Assume that the money spent by all customers at this supermarket has a normal distribution. Using the 5% significance level, can you conclude that the mean amount of money spend by all customers at this supermarket after the campaign was started is more than $65?
question 10 Advertising You are the marketing director for a company that manufactures bodybuilding supplements and you are planning to run ads in Magazine A and Magazine B. Based on readership data, you estimate that each one-page ad in Magazine A will be read by 575,000 people in your target group, while each one-page ad in Magazine B will be read by 275,000 people in your target group. You would like your ads to be read by at least 5 million people in the target group, and, to ensure the broadest possible audience, you would like to place at least four full-page ads in each magazine during the year. Draw the feasible region showing how many pages you can purchase in each magazine. Find the corner points of the region. (Place Magazine A on the x-axis and Magazine B on the y-axis.) Find the corner points of the region. (Order your answers from smallest to largest x, then from smallest to largest y. If an answer does not exist, enter DNE.

QUESTION 1 The Ministry of Health and Social Services (MoHSS) in Namibia intends to embark upon a COVID19 vaccination campaign in the Country. But before deciding which type of COVID19 vaccine to be ordered from the Manufacturers, they first carried out a survey on some countries around the world in order to establish the most preferred vaccine. The findings revealed that: Sixty-eight (68) of them prefer the Pfizer; fifty-two (52) prefer the Moderna; and forty-eight (48) prefer the AstraZeneca. Thirty-six (36) of them prefer Pfizer and AstraZeneca; twenty-two (22) of them prefer Moderna and AstraZeneca; None of the countries prefer AstraZeneca only; 24 prefer Moderna only; 26 prefer Pfizer only; and the remaining 90 countries preferred none of the vaccines. REQUIRED: A.)How many preferred Pfizer or AstraZeneca but not Moderna? B.)What is the ratio (in the simplest form) of the countries that preferred Moderna to those that prefer Pfizer and AstraZeneca? C.)How many countries did not…

Marine biologists have noticed that the color of the outermost growth band on a clam tends to be related to the time of year in which the clam dies. A biologist conducted a small investigation of whether this is true for the species Protothaca staminea. She collected a sample of 55 clam shells in February and 55 clam shells in March. 14 of the shells from February had a dark color on the outermost growth band, whereas 8 of the shells from March had a dark color on the outermost growth band. Carry out a hypothesis test to see if there is a difference in the proportion of shells with a dark outermost growth band between the two months; specifically, if the population proportion in February is higher than March. Let ? = 0.1.Note: Do all calculations as February - MarchA) The point estimate for the true difference in proportion of dark growth bands between February and March is: Note: answer using 4 decimal precisionB) The test statistic, ztest, is: Note: answer using 2 decimal…
Question 9 How Many Social Ties Do You Have?Most US adults have social ties with a large number of people, including friends, family, co-workers, and other acquaintances. It is nearly impossible for most people to reliably list all the people they know, but using a mathematical model, social analysts estimate that, on average, a US adult has social ties with 634 people.1 A survey of 1700 randomly selected US adults who are cell phone users finds that the average number of social ties for the cell phone users in the sample was 664 with a standard deviation of 778. Does the sample provide evidence that the average number of social ties for a cell phone user is significantly different from 634, the hypothesized number for all US adults?1Hampton, K., Goulet, L., Rainie, L., and Purcell, K., ‘‘Social Networking Sites and Our Lives,” Pew Research Center, pewresearch.org, June 16, 2011.
