- "Tiger Woods uses Titleist brand golf clubs" the salesperson says to me. He promises me that my game will improve if I buy the expensive Titleist clubs which are, after all, endorsed by Tiger. But I am a smart consumer, and rather than wasting money on expensive clubs, I first want to know if they work. So, I borrow the Titleist clubs and have 5 randomly selected golfers use them, recording their scores. I also have 6 other randomly selected golfers use my old clubs. Using the data below and the steps of hypothesis testing, test the salesperson's claim that the Titleist clubs will produce a lower score than my clubs (lower is better). Set a = .05. (Note that the scores and scores-squared have already been summed for you at the bottom.

They were asked if they "favor or oppose using federal tax dollars to fund medical research using stem cells obtained from human embryos." Of those polled, 484 were in favor, 399 were opposed, and 121 were unsure. A politician claims that people don't really understand the stem cell issue and their responses to such questions are random responses equivalent to a coin toss. Exclude the 121 subjects who said that they were unsure, and use a 0.01 significance level to test the claim that the proportion of subjects who respond in favor is equal to 0.5. What does the result suggest about the politician's claim? Identify the null and alternative hypotheses for this test. Choose the correct answer below. O A. Ho: p=0.5 H₁: p > 0.5 B.

- 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?Assume that adults were randomly selected for a poll.

- The Diversity, Equity, and Inclusion (DEI) office of a major multinational bank is investigating the process used to make recent hires for financial analysts. The office knows that exactly 10% of all applications were from minority candidates and that exactly 8% of the open positions were filled by members of a minority. For the investigation, the DEI office will take a random sample of 900 applications. Let p be the proportion of minority applicants in the sample. Answer the following. (If necessary, consult a list of formulas.) (a) Find the mean of p. 0 (b) Find the standard deviation of p. 0 (c) Compute an approximation for P(p ≤0.08), which is the probability that there will be fewer minority applicants in the sample than were hired by the bank. Round your answer to four decimal places. 0 X ŚManagement of a company that produces a medical device has carefully selected and screened 220 finished items (packaged, ready to ship). The team agrees that the sample contains 33 defective items, all for various visual defects on the package such as crooked labels, poor seal, errant marks on package, etc. The items are then given to an inspector for classification into “defective” and “non-defective” piles. The inspector ends up rejecting 9 non-defective items, and accepting 11 defective items. The inspector classifies the remaining items in the sample correctly. Find the following (answer as a probability, NOT a percentage. Use 3 decimal places. Notice that alpha = 9/187, Beta = 11/33, and p = 33/220. P(inspector accepts the item and its actually non-defective) =. People in a city are going to vote for one of the three candidates A, B, and C in the next election. In a random sample of 100 people from this city 35 voted for A, 28 voted for B, and the rest voted for C. Perform a significance test and indicate if there is any preferences in the next election for these candidates.

The researcher selects two large cities in each of six provinces of Davao region for the study. In each province, the researcher randomly selects one school of each of the three types and randomly selects a single freshmen class within each school. The scores on a standardized test are recorded for each of 20 students in each classroom. The researcher is concerned about differences in family income levels among the 30 schools, so she obtains the family income for each of the students who participated in the study.iii. blocks iv. experimental unit v. measurement unit vi. replications vii. treatments
