Question
To decide on the number of service counters needed for stores to be built in the future, a supermarket chain wanted to obtain information on the length of time (in minutes) required to service customers. To find the distribution of customer service times, a sample of 1000 customers' service times was recorded. Sixty of these are shown here. 3.6 1.2 1.4 0.2 0.3 2.2 0.8 1.1 2.6 1.0 1.6 1.4 2.0 1.7 0.6 0.5 1.0 0.4 0.0 1.1 4.6 1.1 0.5 1.3 1.4 0.7 0.4 0.3 0.7 5.2 1.8 2.9 1.8 1.6 2.2 1.0 0.8 3.2 1.7 1.0 1.0 0.3 0.1 1.0 0.9 1.3 0.7 1.7 0.7 0.2 0.6 1.8 1.2 1.4 2.4 1.1 1.7 3.1 0.6 1.1 (a) Construct a stem and leaf plot for the data.
