A study is performed to assess the prevalence of use of anti-hypertensive medication (MEDS) in the non-institutionalized U.S. population. The following data are reported for MEDS status of the U.S. population by age-sex group: Table 1 Estimated MEDS Status of the U.S. Population by age and sex group, NHANES study 1999-2018 Males Females Age Group MEDS = yes Na Age Group MEDS = yes Na 18-29 160,617 23,069,867 18-29 168,940 22,132,949 30-39 899,152 18,690,754 30-39 759,532 18,937,878 40-49 2,264,304 18,316,125 40-49 2,257,203 18,816,304 50-59 3,215,688 15,022,905 50-59 4,059,363 15,997,653 60-69 2,936,183 8,400,156 60-69 4,260,975 10,993,805 70-79 1,677,664 4,012,930 70-79 2,953,646 6,012,728 aN = total sample size in specific age-sex groups. a. What is the prevalence of use of MEDS in 40-49 year-old females? b. Suppose a married couple consists of a 54 year-old male and a 48 year-old female. What is the probability that at least one member of the married couple uses MEDS? c. Suppose we assume that all people with hypertension use MEDS. We wish to study the association of hypertension with age, separately for males and females. We categorize age using the same categories as in Table 1. We wish to develop a table as shown in Table 2. Table 2 Association between prevalence of hypertension and age. Males Females Age Group Relative Risk Age Group Relative Risk 18-29 1.0 18-29 1.0 30-39 30-39 40-49 40-49 50-59 50-59 60-69 60-69 70-79 70-79 If we use the age group 18-29 as a reference group, then what is the relative risk (RR) for use of MEDS for a 70-79 year-old male vs. a 18-29 year-old male? Explain what the relative risk means in words (in one sentence). Hint: You only need to compute the RR for 70-79 year-old males. You don’t need to determine the other RR’s for males or any RR for females. d. Suppose three women, Ann (63 years old), Beverly (68 years old) and Cathy (73 years old) meet in a quilting group once per month. What is the probability that exactly one of the women uses MEDS

If we use the age group 18-29 as a reference group, then what is the relative risk (RR) for use of MEDS for a 70-79 year-old male vs. a 18-29 year-old male? Explain what the relative risk means in words (in one sentence).
Hint: You only need to compute the RR for 70-79 year-old males. You don’t need to determine the other RR’s for males or any RR for females.
d. Suppose three women, Ann (63 years old), Beverly (68 years old) and Cathy (73 years old) meet in a quilting group once per month. What is the probability that exactly one of the women uses MEDS?
