Assume that there are 538, 584 males 50 and older alive with CRC, and 31,346 males younger than 50 alive with CRC. What are the prevalence rates (per 100,00) for each age group?
a. Calculate the relative risk of CHD associated with baldness in the stratum of older men. b. Calculate the relative risk of CHD associated with baldness in the stratum of younger men. The investigator was concerned that the results might be confounded by age. She stratified the results, displaying them separately for the older subjects (aged 65 and over) and the younger subjects (aged 40-64). Examine the two tables below Results among older subjects: CHD Yes No Total Bald Hairy...

The recommended daily dietary allowance for zinc among males older than age 50 years is 15 mg/day. An article reports the following summary data on intake for a sample of males age 65-74 years: 2 = 111, x = 12.8, and $ = 6.70. Does this data indicate that average daily zinc intake in the population of all males age 65-74 falls below the recommended allowance? (Use a = 0.05.) State the appropriate null and alternative hypotheses. Horft = 15...
The recommended daily dietary allowance for zinc among males older than age 50 years is 15 mg/day. An article reports the following summary data on intake for a sample of males age 65-74 years: n = 118, x = 12.1, and s = 6.94. Does this data indicate that average daily zinc intake in the population of all males age 65-74 falls below the recommended allowance? (Use a = 0.05.) State the appropriate null and alternative hypotheses. 5:11 PM
