A researcher found that the length of time for five-person student groups to reach a consensus on a sexual harassment policy at the University of Ghana has a normal distribution with u = 2.2 hours and = 0.25. (a) What is the probability that a randomly selected group of students will reach a consensus on a similar policy in less than 1.5 hours? (b) In another experiment with a group of five students, they reached a consensus on the policy option in 1.5 hours. Would you suspect that the group had discussed the policy beforehand? Give reasons for your answer.

A recent study suggested that 70% of all eligible voters will vote in the next presidential election. Suppose 20 eligible voters were randomly selected from the population of all eligible voters. Find the 95% confidence interval of the sampled voters for the next presidential election.
Researchers investigate how the presence of cell phones influence the quality of human interaction. Subjects are randomly selected from a population and divided into an experimental group that is asked to leave their phones in the front of the room and a control group that are not asked to leave their cell phones at the front of the room. Subjects are left alone for 10 minutes and then asked to take a survey designed to measure quality of interactions they had with others in the experiment. What statistical test is appropriate?
In a random sample of 50 patients undergoing a standard surgical procedure, 15 required medication for post operative pain. In a random sample of 90 patients undergoing a new procedure, only 16 required pain medication. a)Are conditions met to perform inference onthis study? b)Construct and interpret a 95% confidence interval for the difference in the proportions of patients needing pain medication between the old and new procedures. c) A physician claims that the proportion of patients who need pain medication is the same for both procedures. Does the confidence interval contradict this claim? Why/Why not?
Researchers conducted an experiment to compare twotreatments for high blood pressure. Their null hypothesis was that the proportion of people whose blood pres-sure would improve is the same for both treatments. The two-sided test resulted in a P-value of 0.07. Which of thefollowing statements is true?A) There is a 7% chance that the drugs are equallyeffective.B) There is a 7% chance the drugs are not equallyeffective.C) The null hypothesis should be rejected at the0.05 level.D) 0 would be contained in the 95% confidence intervalfor the difference in proportions.E) 0 would be contained in the 90% confidence intervalfor the difference in proportions.
9. Nicotine patches are often used to help smokers quit. Does giving medicine to fight depression also help? A randomized double-blind experiment assigned 244 smokers to receive nicotine patches and another 245 to receive both a patch and the antidepressant drug bupropion. After a year, 40 subjects in the nicotine patch group had abstained from smoking, as had 87 in the patch-plus-drug group. (a) Construct and interpret a 99% confidence interval for the difference in the proportion of smokers who abstain when using buproprion and a nicotine patch and the proportion who abstain when using only a patch. (b) Based only on this interval, do you think that the difference in proportion of abstaining smokers is significant? Justify your answer.
Does stretching before exercise reduce the chance of injury? To answer this question, a random sample of 800 athletes was selected and split into two groups based on stretching preference. Of the 450 who do not stretch prior to exercise, 231 suffered an injury during the previous year. Of the 350 who stretch prior to exercise, 55 suffered an injury during the previous year. Is there enough evidence to conclude that stretching prior to exercise reduces the chance of injury based on these data? Calculate the test statistic. You must show your work for full credit.
A study is being performed to see if there is a correlation between theconcentration of chromium in the blood and a suspected disease. Bloodsamples from a series of volunteers with a history of the disease and otherindicators of susceptibility are analyzed and compared with the results fromthe analysis of samples from healthy control subjects. From the followingresults, determine whether the difference between the two groups can beascribed to chance or whether they are real (i.e. Do the two groups havestatistically different results at the 95% confidence limit?). [Hint: You mustdecide if the standard deviations of the two methods are statistically thesame first.]
