The following is a random sample of sixentertainment expenses (dinner costs for four people) from expense reports submitted by members of the sales force.$357 $332 $309 $345 $325 $339334.50334.50334.50Enter tolerance intervals1) Calculatex", s^2, and s for the expense data.2) Assuming that the distribution of entertainment expenses is approximately normally distributed, calculate estimates of tolerance intervals containing 68.26 percent,95.44 percent, and 99.73 percent of all entertainment expenses by the sales force.3) If a member of the sales force submits an entertainment expense (dinner cost for four) of $390, should this expense be considered unusually high (and possiblyworthy of investigation by the company)?
