M6 An epidemiologic study was conducted at a highschool to determine if participation in sports wereassociated with methicillin-resistantStaphylococcus aureus (MRSA) skin infections. Theinvestigators identified 127 laboratory-confirmedMRSA skin infection cases and 381 controls fromthe high school. Based on review of school recordsit was determined that among the MRSA cases,were on the wrestling team and only 4 controlswere on the wrestling team.12What type of study design is this?What is the best measure of association, in theabove study, to use to examine the exposuredisease relationship?how many more times likely were high schoolstudents with a MRSA skin infection to be on thewrestling team than students who did not haveMRSA?

What is an experiment?
An epidemiologist found five cases of “big toe cancer” in the Yukon Territory. Because there were only a few cases, the epidemiologist decided to conduct a matched case-control study to determine whether shoe size larger than 9 is a risk factor for big toe cancer. Cases were individually matched to one control for daily activity, history of athlete’s foot, and history of ingrown toenails. The following data were gathered: Shoe size > 9 Pair Case Control 1 Yes No 2 No No 3 No Yes 4 Yes Yes 5 No Yes Compute the proper measure of association. Interpret your results. If you were to investigate a rare cancer in Lynchburg, where might you look for data? What would be necessary legally and ethically to be able to utilize this data set(s)?

The Human Resources Department is studying absenteeism with employees. They have noticed an unacceptable level of absenteeism that is believed to be related to the general health of the employees. Twelve months ago, a fitness program for employees was started at the company. To evaluate the program, a random sample of eight participants were studied before the fitness program began and the same eight participants were studied twelve months later. The Human Resources Department believes the number of absences should change over the twelve months. Before After Difference Employee 1. What is dbar? 2. What is tcrit? 3. What is at? 4.

According to areport on consumer fraud and identity theft, 22% of all complaints during one year were for identity theft. In that year, Michigan had 322 complaints of identity theft out of 1457 consumer complaints.

A researcher was interested in whether there were differences in the level of activity in children who had been diagnosed with ADHA depending on whether they had received no treatment, were on Ritalin, or were in a behavior management program. He recruited 90 children with ADHD to participate, and randomly assigned each child to one of the three groups. The number of classroom disturbances during a 1 hour period was measured for each child. Which statistical test would be best to determine if there is a significant difference between groups?
A study is designed to test whether there is a difference in mean daily calcium intake in adults with normal bone density, adults with osteopenia (a low bone density which may lead to osteoporosis) and adults with osteoporosis. Adults 60 years of age with normal bone density, osteopenia and osteoporosis are selected at random from hospital records and invited to participate in the study. Each participant's daily calcium intake is measured based on reported food intake and supplements. The data are shown below. Is there a statistically significant difference in mean calcium intake in patients with normal bone density as compared to patients with osteopenia and osteoporosis?
A research study wishes to examine if there is a relationship between type of exercise (marathon, yoga, or cross fit) and getting hypertension (or not getting hypertension). Of the 78 marathon runners, 14 get hypertension. Of the 63 yoga practitioners, 6 get hypertension. Among the 54 CrossFit athletes, 16 get hypertension. What is the critical value for the test statistic?
Most alpine skiers and snowboarders do not use helmets. Do helmetsreduce the risk of head injuries? A study in Norway compared skiers and snowboarders who suffered head injuries with a control group who were not injured. Of 578 injured subjects, 96 had worn a helmet. Of the 2992 in the control group, 656 wore helmets. Is helmet use less common among skiers and snowboarders who have head injuries?
In a major urban area, the percentage of male drivers between the ages of 19 and 29 who did not regularly use seatbelts was 28%. After a major radio and television campaign and stricter enforcement by the local police, researchers want to know if the percentage of male drivers between the ages of 19 and 29 who did not regularly use seatbelts has decreased. They poll a random sample of 100 males between the ages of 19 and 29 and find the percentage who didn’t wear their seatbelt was 24%. (a) Identify the population, parameter, sample and statistic.(b) State appropriate hypotheses for performing a significance test.
