5. Suppose the number of days it takes you to get a flu shot after it is available follows this equation: Y, 30 - 2Xi where Yİ is the number of days until you get the flu shot, and Xi is the number of people you know whọ have the flu. Further, suppose on average you know 2.3 people who have the flu, with standard deviation 5. Suppose that the population has size m 10 (a) Find the average time until you get the flu shot after it is available b) Find the standard deviation of time until you get the flu shot after it is available.(c) What is Y?

    Activity Four: Confidence Intervals – Sigma unknown Suppose it takes, on average, 10 days to deliver a computer to a customer. This statistic was generated from observing 100 deliveries. The population standard deviation is unknown, but from your observation of 100 deliveries, you calculate the sample standard deviation to be 2 days. The shipping manager would like to construct a 95% and 99% confidence interval (CI) estimate of delivery time. You estimate the mean delivery time to fall between ___...
