Two different blood pressure medicines are being compared to determine if the average reduction in blood pressure is the same for each medication. The goal of the study is to determine if the medications differ. Twenty men age 50-60 years old are selected for the study. Ten men are chosen at random to receive the first medication and the other 10 men receive the second medication. Each of the 20 men is monitored for one month to determine the change in blood pressure over that time. Minitab provides the 95% confidence interval for (mu1 - mu2) (2.63, 14.18) a. Interpret this 95% CI. b. What assumptions (be specific) are necessary to construct this CI?

2. A researcher wants to measure the job satisfaction levels of the employees of two fast food company located in Manila. The researcher has used a questionnaire consisting of ten questions related to job satisfaction levels of the employees. The researcher has used a rating scale from 1 to 4 where 1 is the lowest score and 4 is the highest score. So, a maximum score of 40 and a minimum score of 10 can be obtained. The researcher has randomly selected 15 employees from the first company and 17 employees from the second company. The scores obtained from these employees are given below: First Company: 32 40 31 33 32 30 30 32 31 32 34 32 38 32 28 Second Company: 25 28 23 27 24 26 27 22 25 26 34 25 23 22 29 27 24 Taking 5% as the alpha level, examine the significant difference in terms of job satisfaction level between the employees of the two companies.

Suppose that the insurance companies randomly surveyed 400 drivers and found that 320 claimed they always buckle up. We are interested in the population proportion of drivers who claim they always buckle up. Use this scenario for the next 4 questions. What is the meaning of p ^ in the context of this scenario? Group of answer choices the proportion of drivers who claim they always buckle up in the POPULATION Neither of these the proportion of drivers who claim they always buckle up in the SAMPLE What is the value of p ^ in the context of this scenario? f you wanted to estimate the true percentage of drivers who claim they always buckle up to within 1% error with 95% confidence, how many drivers would you need to survey? You may use the pilot study as a preliminary estimate of p ^.

UCLA conducted a survey of more than 263,000 college freshmen from 385 colleges in fall 2005. The results of students' expected majors by gender were reported in The Chronicle of Higher Education (2/2/2006). Suppose a survey of 5,000 graduating females and 5,000 graduating males was done as a follow-up last year to determine what their actual majors were. The results for males are shown in the table below. The second column in the table does not add to 100% because of rounding.Conduct a goodness-of-fit test to determine if the actual college majors of graduating males fit the distribution of their expected majors.

7. A new drug study was conducted by a drug company. In the study, 10 people were chosen at random to take Vitamin X for 3 months and then have their cholesterol levels checked. In addition, 10 different people were randomly chosen to take Vitamin Y for 3 months and then have their cholesterol levels checked. All 20 people had cholesterol levels between 8 and 10 before taking one of the vitamins. The drug company wanted to see which of the 2 vitamins had the greatest impact on lowering people's cholesterol. The following data was collected: Vitamin X 7.27.5 5.2 6.5 7.7 10 6.47.6 7.77.8 Vitamin Y 4.8 4.44.5 5.1 6.5 8.03.1 4.6 5.2 6.1 (a) Draw a box-and-whisker plot for both sets of data on the same number line. (b) Use the double box-and-whisker plots to compare the 2 vitamins and provide a conclusion for the drug company. (e) State the skewness of both distributions and justify your answer.
