5.6.2 In the report cited in Exercise 5.6.1 [A-8], the Census Bureau stated that for Americans in the age group 18-24 years, 64.8 percent had private health insurance. In the age group 25-34 years, the percentage was 72.1. Assume that these percentages are the population parameters in those age groups for the United States. Suppose we select a random sample of 250 Americans from the 18-24 age group and an independent random sample of 200 Americans from the age group 25-34: find the probability that po - p, is less than 6 percent.5.5.4 Gallagher et al. [A-6] reported on a study to identify factors that influence women's attendance at cardiac rehabilitation programs. They found that by 12 weeks post-discharge, only 64 percent of eligible women attended such programs. Using 64 percent as an estimate of the attendance percentage of all eligible women, find the probability that in a sample of 45 women selected at random from the population of eligible women less than 50 percent would attend programs
