3. A recent study concerning knee injuries of football players compared two types of football shoes. Out of a randomly chosen group of 1440 players, 240 used multicleated shoes and 1200 used more conventional football shoes. All played on natural grass. Of those using the multicleated shoes, 13 suffered knee injuries. Of those using conventional shoes, 78 suffered knee injuries. (a) Test the hypothesis that the probability of a knee injury is the same for both groups of players. Use the 5 percent level of significance. (b) Are the given data strong enough to establish that the multicleated shoes are superior to the conventional ones in terms of reducing the probability of a knee injury?

The histogram below gives the length of service of members of the Department of English at a particular university. The classes, in years of service, are 0−−4.9, 5−−9.9, etc., and the vertical axis represents the number of faculty. 1) What percent of the department faculty have less than 15 years of service? 2) If a member of the department is chosen at random to serve on a university committee, what is the probability (in decimal form) that the chosen representitive will have between 5 and 45 years of service? 3) What is the probability the representative above will have less than 20 years of service given that the person has less than 25 years of service?
A study showed that in 1990, 47% of all those involved in a fatal car crash wore seat belts. Of those in a fatal crash who wore seat belts, 46% were injured and 26% were killed. For those not wearing seat belts, the comparable figures were 43% and 51%, respectively. Find the probability that a randomly selected person who was unharmed in a fatal crash was not wearing a seat belt.
Fewer young people are driving. In 1995, 63.9% of people under 20 years old who were eligible had a driver's license. Bloomberg reported that percentage had dropped to 41.7% in 2016. Suppose these results are based on a random sample of 1,200 people under 20 years old who were eligible to have a driver's license in 1995 and again in 2016.

Suppose an investigator has studied the possible association between the use of a weight-loss drug and a rare central nervous system (CNS) disorder. He samples from a group of volunteers with and without the disorder, and records whether they have used the weight-loss drug. The data are summarized in the attached table: What is the estimated the odds ratio for the presence of a CNS disorder, comparing people who have used the weight-loss drug to those who have not? What test would you use to evaluate the null hypothesis of no association between weight-loss drug use and presence of a CNS disorder?
The M&M/Mars candy company does a lot of market research to determine the most appealing mix of colors in M&M candies. Recently, one mix was: Purple 20%; Yellow 20%; Red 20%; Orange 10%; Green 10%; Blue 10% and Brown 10%. Suppose you reach into a bag of M&M candies and draw out ONE candy at random. What is the likelihood of drawing a Purple candy?
A study reported that about 40% of high school students have tried out for a sport at their school. To find out if this applies to Jessica’s school, she surveyed an SRS of 20 students. Nine of them said that they had tried out for a sport. To see if this result is surprising, a simulation is to be conducted to estimate the probability of obtaining a sample result as high as this one. Let 0–3 represent students who tried out for a sport and 4–9 represent students who did not try out for a sport. Using the line of random numbers to run one simulation, what proportion of students tried out for a sport? 0.40 0.45 0.50 0.60
A pharmaceutical company is running trials on a new test for anabolic steroids. The company uses the test on 400 athletes known to be using steroids and 200 athletes known not to be using steroids. Of those using steroids, the new test is positive for 375 and negative for 25. Of those not using steroids, the test is positive for 25 and negative for 175. What is the relative frequency of a false negative result (the probability that an athlete using steroids will test negative)? (Round your answer to two decimal places.) What is the relative frequency of a false positive result (the probability that an athlete not using steroids will test positive)? (Round your answer to two decimal places.)
