- Present at least three graphs that help explain these three variables for the state in which you live.
- Determine the mean, median, mode, standard deviation, and variance for the three variables for the counties within the state of your residence.
- Assess each of your three variables for normality.
- Determine the Z score for each of the three variables for your home county plus two others within the state of your residence, are any of these counties considered extreme outliers?
- What is the probability that a randomly selected citizen from the state of your residency will come from a county with a higher mean for each of the three variables you selected?
