Prepare answers for the following questions within your group that you can share with the class. {1} A "healthy\" birthweight for babies born in the U5. is currently set at 2300 grams; the average birthweight for babies born to women living in poverty tends to be lower than 2300 grams. Recently, a local hospital introduced an innovative new prenatal care program to reduce the number of low birthweight babies born in the hospital, especially for women living in poverty. {a] What is your population? {b} What is your population parameter of interest? {c] What are the null and alternative hypotheses for the parameter you stated in part [b]? {2} Continuing with question [1], In the first year of the program, 25 mothers, all of whom live in poverty, participated in this program; hospital records reveal that the babies born to these women had a mean birthweight of 3033 grams, with a standard deviation of 603 grams. {a] What is the value of your tstatistic? Give- a n interpretation for this statistic. {b} Use the \"One-Sample ttest\" Excel spreadsheet to compute your p-value: state your p-value. {c] What conclusion do you reach regarding the null and alternative hypotheses you stated in question [1}? {3} The National Center for Health Statistics [NCHS] published a report that indicated that in 2002, Americans paid an average of 53,302 per year on health care and prescription drugs. An investigator hypothesizes that in 2005 expenditures have decreased primarily due to the availability of generic drugs. To test the hypothesis, a sample of 100 Americans are selected and their expenditures on health care and prescription drugs in 2005 are measured. The sample mean and standard deviation of the 100 Americans were $3,190 and 5890, respectively. {all What is your population? {b} What is your population parameter of interest? {cl What are the null and alternative hypotheses for the parameter you stated in part [b]? {d} Use the \"OneSample ttest" Excel spreadsheet to decide what conclusion you reach regarding the hypotheses you stated in {c}. {4} Return to the I'v'lEF'S data and answer the following questions. {all Use the data to compute a 95% confidence interval for mean BMI in the US population. {b} A BMI larger than 25 and less than 30 is considered overweight. Does your answer to {a} support or refute the claim that the US population tends to be overweight, on average? {5} During a political debate, a political candidate states that the average American family has an income of SE-fyear. Based upon the MEPS data, do you agree or disagree with this statement. Provide evidence for your answer. {6} During the debate, the same candidate also states that the average American family spends $560fyear on out-ofpocket [not paid by any insurer} medical expenses. Based upon the MEPS data; do you agree or disagree with this statement. Provide evidence for your
