6. A poll was conducted to understand Americans' attitude regarding medical visits. The poll was conducted using a random sample of 3,200 U.S adults. (a) In poll, 42% said they would be "very concerned" about being exposed to the novel coronavirus (COVID-19) at a doctor's office or hospital. Calculate and interpret a 98% confidence interval for the true proportion of all U.S. adults that are very concerned about being exposed to COVID-19 at a doctor's office or hospital. (5 points) (b) 48% out of 1500 women, and 35% out of 1700 men sampled said they were "very concerned" about being exposed to COVID-19 at a doctor's office or hospital. Cal- culate and interpret a 95% confidence interval for the difference in proportion of those "very concerned" between women and men. (5 points) (c) Conduct a hypothesis test for whether the proportion of women being "very con- cerned" about being exposed to COVID-19 from a doctor's office or hospital is higher than that of men. Show all steps and state your conclusion (5 points)
