The following is a small data set of 25
observations. I want you to calculate some statistics by
hand to cement the class material. You can use the regular formula
for the variance or the computational formula - I’m just interested
in the correct result. If you use the computational formula, you
will want to calculate a separate row of each value squared in
order to calculate the Sum(x^2). Excel can be used to solve
this problem.

Data was collected on the gas mileage (miles per gallon = MPG)
for a select group of 11 SUVs; see the Excel descriptive statistics
file below.
After Constance viewed this data, she said "This data is very
symmetrical." Clearly state why you do or why you
don't agree with Constance's statement.
Constance continues... "I'm a little confused though. Since a
symmetrical data set should follow the empirical rule, why doesn't
