Suppose 1495 Valencia College students were selected at random from the entire student body and given an experimental H1N1 flu shot. All 1495 were exposed to the flu, but only 332 of them actually ended up sick with the flu. Let p represent the probability that the flu shot will be successful. (Read this carefully!) A. Find the point estimate for the population proportion from this study. Show your simplified fraction for the point estimate. Use proper notation. B. Build a 98% confidence interval for the real population proportion by hand using the formula. Draw a picture that represents the problem and clearly indicate your final answer CUse a complete sentence or two to interpret your confidence interval
