For Questions 1-10, please identify the test statistic that should be conducted, I am double checking my work, please have the correct test statistic listed. 1. A researcher wishes to see if the average weights of newborn male infants are different than the average weights of newborn female infants. The researcher recruits 10 male infants and 10 female infants (via parental consent) to conduct her study. 2. Two types of antibiotics (amoxicillin and penicillin) were tested to see how long (in minutes) each remained in the bloodstream of patients with an infectious disease. The researcher also wanted to know if gender had an effect on how long the antibiotics remain in the bloodstream. 3. The per-patient costs (in thousands of dollars) for health care were collected in three different areas of Des Moines. Is there a difference in the means of the costs between the three areas? 4. A researcher wishes to see if there is a difference in the cholesterol levels of United States adults over 40 years of age and adults under 40 years of age. The researchers collects a sample of adults over 40 years of age and a sample of adults under 40 years of age to conduct his study. 5. A researcher conducted a study of three different diets and two different exercise programs. Seven randomly selected subjects were assigned to each condition for one month. The researcher wants to know if diet and exercise program have an effect on the amount of weight lost and if the interaction between diet and exercise program has an effect on weight lost. 6. The Medical Rehabilitation Education Foundation reports that the average cost of rehabilitation for stroke victims is $24,672. A researcher recruits a random sample of 35 stroke victims in Iowa who report an average cost of $35, 234 and a standard deviation of $6,349. Can it be concluded that the average cost of stroke rehabilitation in Iowa is different than that of the population? 7. The average 1-year old (both genders) is 29 inches tall with a standard deviation of 3 inches. A random sample of thirty 1-year olds in a large day care franchise resulted in a mean height of 27 inches. Can it be concluded that the average height of 1-years olds in the given sample differs from that of the population? 8. A random sample of 26 speech-language pathologists from Iowa reported an average salary of $45,350 with a standard deviation of $1,659, while a random sample of 26 occupational therapists from Iowa has an average salary of $50,215 with a standard deviation of $4,116. Is there a significant difference between the two groupsâ€™ salaries? 9. The number of protein grams per serving of four different kinds of meat (i.e., chicken, fish, beef, and pork) are collected. The researcher wants to know if there are differences between the kinds of meat for grams of protein per serving. 10. A researcher wishes to determine if an educational intervention will reduce the number of fat grams consumed among overweight children.
