A flu shot is administered during flu season. We look at the effect of the shot on individuals who received the shot versus those who did not. In a sample of 100 patients that received the flu shot, the average recovery time after being infected with the flu was 4 days with a standard deviation of 1 day. What is a 95% confidence interval for the population average recovery time? (3.99, 4.01) (3.80, 4.20)
