Question #11 A tamoxifen study claims that a combination of chemotherapy and the hormone therapy tamoxifen is more effective than tamoxifen alone in preventing breast cancer. In the study, a group of researchers from the U.S. and Canada studied 1477 postmenopausal women with early-stage breast cancer. The women were randomly assigned to one of three study groups. The first group of 361 received tamoxifen alone on a daily basis for five years. The second group of 566 received chemotherapy and tamoxifen for six months, and then completed five years of tamoxifen treatment. And the third group of 550 received chemotherapy alone for six months followed by five years of tamoxifen treatment. All 1477 patients knew which treatment they were receiving.In this study, which is the control group? the third group of 550 that received chemotherapy alone for 6 months and then tamoxifen for 5 years the second group of 566 that received tamoxifen and chemotherapy concurrently for 6 months the first…
Question 23: The National Institute of Mental Health published an article stating that in any one-year period, approximately 9% of American adults suffer from depression or a depressive illness. Suppose that in a survey of 2000 people in a certain city, 10% of them suffered from depression or a depressive illness. Conduct a hypothesis test to determine if the true proportion of people in that city suffering from depression or a depressive illness is more than the 9% in the general adult American population. Test the relevant hypotheses using a 10% level of significance. Give answer to at least 4 decimal places. What are the correct hypotheses? (Select the correct symbols and use decimal values not percentages.) H0: H1: Based on the hypotheses, find the following: Test Statistic = p-value = Based on the above we choose to The correct summary would be: that the true proportion of people in that city suffering from depression or a…
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 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…
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 a) The manufacturer of a gasoline additive claims that the use of this additive increases’ gasoline mileage. A random sample of 6 cars was selected, and these cars were driven for one week without the gasoline additive and then for one week with the additive. The following table gives the mileage (in miles per gallon) for these cars with and without the additive: Car 1 2 3 4 5 6 Mileage Without Additive 24.6 28.3 18.9 23.7 15.4 29.5 Mileage With Additive 26.3 31.7 18.2 25.3 18.3 30.9 Assuming mileage are normally distributed, can you conclude that the use of the gasoline additive increases mileage at the 2.5% significance level? a) Statistical significance is not the same as practical significance. Explain with an example, the stated claim. b) What general form does the alternative hypothesis take for one-way between-subjects analysis of variance? Why can’t it be summarized in a single mathematical statement?
