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:
sample 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
mean 13 11 5 14 9 10 12 13 10 11 14 6 8 6 9
range 9 13 6 10 11 17 14 17 12 12 13 8 11 13 15
Subsequently, samples of size 5 were taken from the process every week for the next 10 weeks. The times were measured and the following results obtained:
Sample 16 17 18 19 20 21 22 23 24 25
mean 9 11 6 12 14 15 10 19 17 15
range 9 13 8 6 14 15 13 12 10 8
