Fifteen samples of five completed mortgage transactions each were taken during a period when the process was believed to be in control. The times to complete the transactions were measured. The means and ranges of the mortgage process transaction times, measured in days are as follows: 6 Sample Mean Range 1 19 6 2 17 12 3 11 5 4 20 9 5 15 10 15 14 7 18 13 8 19 16 9 16 11 10 17 11 11 18 11 12 12 7 13 14 10 14 12 12 15 15 14 16 13 9 17 17 12 18 12 7 19 18 5 20 20 13 21 22 15 22 16 12 23 25 11 24 25 23 21 9 7 Subsequently, samples of size 5 were taken from the process every work for the next 10 weeks.
