Three samples are taken comprising 120 doctors, 150 advocates and 130 * university teachers. Each person chosen is asked to select one of the three categories that best represents his teeling toward a certain national policy. The three categories are in favour of policy (F), against the policy (A), and indifferent toward the policy (). The results of the interviews are given below : Reaction Occupation F A Total Doctors 80 30 10 120 Advocates 70 40 40 150 University Teachers 50 50 30 130 Total 200 120 80 400 On the basis of this data can it be concluded that the views of Doctors, Advocates. and University teachers are homogeneous in so far as National Policy under discussion is concerned.

- A study classified each of 134 lawyers into one of four groups based on observation and an interview. The 62 lawyers in group A were categorized as having high levels of stimulation and support and average levels of public spirit. The 52 lawyers in group B had low stimulation, average support, and high public spirit. Group C contained 7 lawyers with average stimulation, low support, and low public spirit. The 13 lawyers in group D were assessed as low on all three criteria. Salary levels for these four groups were compared. The sample means were 7.87 for group A, 7.47 for group B, 5.14 for group C, and 3.69 for group D. The F ratio calculated from these data was 25.60. a. Prepare the complete analysis of variance table. b. Test the null hypothesis that the population mean salaries are the same for lawyers in these four groups.In a large clinical trial, 394,003 children were randomly assigned to two groups.

- An insurance company is thinking about offering discounts on its life insurance policies to nonsmokers. As part of its analysis, the company randomly selects 200 men who are 60 years old and ask them if they smoke at least one pack of cigarettes per day and if they have ever suffered from heart disease. 10 out of the 38 smokers had suffered from some type of heart disease and 12 out of 150 nonsmokers had suffered from some type of heart disease. Can we conclude at the 5% level of significance that smokers have a higher incidence of heart disease than nonsmokers? (Don't hand writing solution)If a hurricane was headed your way, would you evacuate? The headline of a press release states, "Thirty-two Percent of People on High-Risk Coast Will Refuse Evacuation Order, Survey of Hurricane Preparedness Finds." This headline was based on a survey of 4229 adults who live within 20 milesof the coast in high hurricane risk counties of eight southern states. In selecting the sample, care was taken to ensure that the sample would be representative of the population of coastal residents in these states. (a) Use this information to estimate the proportion of coastal residents who would evacuate using a 98% confidence interval. (Round your answers to three decimal places.)( , )To investigate whether there is a significant difference between two regions of a state in the percent of voters who intend to vote for the incumbent governor in the next election, a polling agency interviewed 300 randomly selected voters from the north of the state and 400 randomly selected voters from the south of the state. Of those interviewed, 200 from the north and 325 from the south indicated they intended to vote for the incumbent governor in the next election. Which of the following is the most appropriate method for analyzing the results? A one-sample zz-test for a sample proportion A A one-sample zz-test for a population proportion B A two-sample zz-test for a sample proportion C A two-sample zz-test for a difference in sample proportions D A two-sample zz-test for a difference in population proportions E
