Question

Need assistance with d, e and f.

Styles PART 2 Suppose that 800 students were selected at random from a student body of 20,000 and given shots to prevent a certain type of flu. All 800 students were exposed to the flu, and 600 of them did not get the flu. Let p represent the probability that the shot will be successful for any single student selected at random from the entire population of 20,000. Let q be the probability that the shot is not successful. (a) What is the number of trials n? (b) What is the number of successes x? (c) What is the point estimates for p and q? (d) Would it seem that the number of trials is large enough to justify a normal approximation to the binomial? (e) Compute the margin of error, E for a 99% confidence interval for p (f) Compute a 99% confidence interval for p. (o What does the confidence interval you just computed mean in the context of this application? Accessibility: Good to go
