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.

a. Construct a stem and leaf plot for the data.
b. What fraction of the service times are less than or equal to 1 minute?
c. What is the smallest of the 60 measurements?
