The downtime per day for a certain computing facility has averaged 4.0 hours and a standard deviation of 1.98 for the last year. Find the probability that the average daily downtime a. for a period of 20 days is between 1 and 5 hours. b. for a period of 15 days is less than 6 hours. Note: Draw the standard normal curve for each item above. Shade the area that corresponds to the required probability calculation.
