Create a histogram for the Sales/SqFt variable and answer the following questions:
Is the distribution symmetric? If not, what is the skew?
Are there any outliers? If so, which one(s)?

BachDeg% versus Sales/SqFt
MedIncome versus Sales/SqFt
MedAge versus Sales/SqFt

Descriptive Statistics Analysis Essay
Based on your findings above, assess which expansion criteria seem to be more effective. Is there any expansion criterion that could be changed or eliminated? If so, which one and why?
Based on your findings above, does it appear as if the loyalty card is positively correlated with sales growth? Would you recommend changing this marketing strategy?
Based on your previous findings, recommend marketing positioning that targets a specific demographic. (Hint: Are younger people patronizing the restaurants more than older people?)
Indicate what information should be collected to track and evaluate the effectiveness of your recommendations. How can this data be collected? (Hint: would you use survey/samples or census data?)
