A company's contractual "trigger" point for a union absenteeism penalty is a certain distance above the mean days missed by all workers. Now the company wants to switch the trigger to a certain distance above the median days missed for all workers. (a) Check the appropriate distribution of missed days for all workers (symmetric, skewed left, skewed right). Symmetric Skewed Left Skewed Right (b) Pick the probable effect on the trigger point of switching from the mean to the median. Switching would trigger the penalty sooner. Switching would trigger the penalty later. Switching will not trigger a penalty. (c) What position would the union be likely to take on the company's proposed switch? The union would oppose the change. The union would be neutral. The union would agree to the change.

(20 points) a bank has been receiving complaints from real estate agents that their customers have been waiting too long for mortgage confirmations. the bank prides itself on its mortgage application process and decides to investigate the claims. the bank manager takes a random sample of 20 customers whose mortgage applications have been processed in the last 6 months and finds the following wait times (in days): 5, 7, 22, 4, 12, 9, 9, 14, 3, 6, 5, 15, 10, 17, 12, 10, 9, 4, 10, 13 assume that the random variable x measures the number of days a customer waits for mortgage processing at this bank, and assume that x is normally distributed. 2a. find the sample mean of this data (x ě…). 2b. find the sample variance of x. find the variance of x ě…. for (c), (d), and (e), use the appropriate t-distribution 2c. find the 90% confidence interval for the population mean (îľ). 2d. test the hypothesis that îľ is equal to 7 at the 95% confidence level. (should you do a one-tailed or two-tailed test here? ) 2e. what is the approximate p-value of this hypothesis?
