You are given the following data for the number of times a population of six
families dined out during the previous month:

4 6 9 4 5 7

a. Compute the mean, median and mode for this data.
b. Compute the range for this data.
c. Compute the variance and standard deviation.
d. Assume that these data represent a sample rather than a population. Compute the variance and standard deviation. Discuss the difference between the value computed here and in part b.
