Savings banks are permitted to sell a form of life insurance called savings bank life insurance (SBLI). The approval process consists of underwriting, which includes a review of the application, a medical information bureau check, possible requests for additional medical information and medical exams, and a policy compilation stage during which the policy pages are generated and sent to the bank for delivery. The ability to deliver approved policies to bank customers in a timely manner is critical to the profitability of this service to the bank. During a period of one month, a random sample of 27 approved policies was selected, and the following total processing times in days, were recorded; 73 19 16 64 28 28 31 90 60 56 31 56 22 18 45 48 17 17 17 91 92 63 52 51 69 16 17 Find the interquartile range (IQR) of the given set of data. a. 45 b. 43 c. 44 d. 42
