Scientific research on popular beverages consisted of 65 studies that were fully sponsored by the food industry, and 35 studies that were conducted with nocorporate ties. Of those that were fully sponsored by the food industry, 14 % of the participants found the products unfavorable, 24 % were neutral, and 62% found the products favorable. Of those that had no industry funding, 40 % found the products unfavorable, 18 % were neutral, and 42 % found theproducts favorable.What is the probability that a participant selected at random found the products favorable?4If a randomly selected participant found the product favorable, what is the probability that the study was sponsored by the food industry?If a randomly selected participant found the product unfavorable, what is the probability that the study had no industry funding?

Izmir University of Economics students evaluate the social services in school by a questionnaire within three rating categories (A, B, and C). Suppose that in the past year, of the questionnaires on social service issues throughout the university, 50% were rated A, 30% were rated B, and 20% were rated C. Of the questionnaires rated A, 30% were answered by the engineering students, 30% by students from business faculty, and 40% by fine arts students. Of the questionnaires rated B, 50% were answered by engineering students, 10% by students from business faculty, and 40% by fine arts students. Of the questionnaires rated C, 80% were answered by engineering students, 5% by students from business faculty, and 15% by fine arts students. Complete (a) through (c) below. a. If a new questionnaire is answered by an engineering student, what is the probability that it will receive an A rating? (Round to three decimal places as needed.) b.

4. A study was conducted among men in the United States in order to find out whether a mother’s use of hormones during her pregnancy affected her son’s risk of developing testicular cancer. Investigators selected 1000 men who were hospitalized for testicular cancer, and 1000 men of the same ages hospitalized for other, non-cancer conditions. The study found that of the men with testicular cancer, 400 of their mothers had used hormones during that pregnancy; and of the men with other non-cancer conditions, 100 of their mothers had used hormones during pregnancy A.Calculate the relative measure of association identified aboveB.Calculate a 95% confidence interval for the relative measure of association you identified above.

Deforestation is a serious problem throughout much of India. An article discusses the social forces that influence forest management policies in three Indian states: Haryana, Bihar, and Uttar Pradesh. The forest quality in Haryana is somewhat degraded, in Bihar it is very degraded, and in Uttar Pradesh it is well-stocked. In order to study the relationship between educational levels and attitudes toward forest management, random samples of adults in each of these states were surveyed and their educational levels were ascertained. The numbers of adults at each of several educational levels were recorded. The data are presented in the following table (see image). A.Find the P-value B.State a conclusion. Can you conclude that the educational levels differ among the three states?
A market research group is interested in estimating the market share of three airline companies, A, B and C, operating on a particular flight path. These three airlines are the only companies operating on this route. Airline B claim that they have 50% of the business with the remaining percentage shared equally amongst airlines A and C, i.e. 25% each. The market research group decide to carry out an independent study and question a random sample of 97 people visiting an airport on a particular day. Each person was given price, timetables and service details of flights on this route for each of the three airlines. Provided with this information they were asked to select their airline of choice.The survey revealed the following observed frequencies Airline A - 26 Aurline B - 49 Airline C - 22 Test if there is any evidence to suggest that the airline's claim is incorrect, at significance level α = 0.05. Complete the test by answering the following questions : Which of the following is the…
