Suppose that the duration of a particular type of criminal trial is known to have a mean of 18 days and a standard deviation of 6 days. We randomly sample 9 trials.Give the distribution of ΣX. Find the probability that the total length of the 9 trials is more than 188 days. (Round your answer to four decimal places.).70 percent of the total of 9 of these types of trials will last more than how long?
