2, PART A Let X be the number of people in our sample who are age 65 or older. X has a binomial distribution with parameters (n,p). Provide the value of n and an interpretation of p. (In other words, we know the numerical value of n, but p is unknown, so just describe what 'p' means.) PROBLEM 2, PART B What proportion ( of people are 65 or older in our sample? PROBLEM 2, PART C Adults ages 65 and older make up 16% of the U.S. population. Assume our sample of 406 people is an SRS of US adults and write the distribution of p-hat, the sample proportion
