5. Is lack of sleep causing traffic fatalities? A study conducted under the auspices of the National Highway Traffic Safety Administration found that the average number of fatal crashes caused by drowsy drivers each year was 1550 (Business Week, January 26, 2015). Assume the annual number of fatal crashes per year is normally distributed with a standard deviation of 300 and a mean of 1550.

1. 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 C. Use a complete sentence or two to interpret your confidence interval.
