Suppose that the duration of a particular type of criminal trialis known to have a mean of 21 days and a standard deviation ofseven days. We randomly sample nine trials.
19. Find the probability that the sum of the 9 trials isless than 160. Round to five decimal places.
20. Find the probability that the sum of the 9 trials isless than 170 and greater than 199. Round to four decimalplaces.
21. Find the probability that the sum of the 9 trials isbetween 170 and 199. Round to four decimal places.
