You are a manager in one of the branches of a restaurant. The area manager assigned
you to analyze the statistical data of the ages of the customers who eat in your
restaurant. From the survey forms, the following are the summary of their evaluations:
Age - - - - - - - No. of Customers
16–20 - - - - - -32
21–25 - - - - - -40
26–30 - - - - - -15
31–35 - - - - - - 29
36–40 - - - - - - -11
Using the given data, determine how spread out the ages of the customers are using
measures of variability. Find out what ages fall within one standard deviation from the
mean. Knowing this, what range of ages or what age group should the restaurant give
more focus on, and what products do you think should the restaurant come up with to
generate higher sales? Submit a typewritten report detailing your answers, solutions, and
explanations to these questions.
