You are given the following datafor 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, medianand modefor this data.

b. Compute the rangefor this data.

c. Compute the varianceand 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.
