The following times(in minutes) to process hot-rolled steel are observed for a random sample of size 10:
5.4 6.2 7.9 4.8 7.5
6.2 5.5 4.5 7.2 6.2
(a) Find the mean, median, and mode of the processing times. Interpret the differences between them.
(b) Compute the range, variance, and standard deviation of the processing times and interpret them.
