- Solve for the Standard Deviation for each column in the above table.
- Conduct a one-tailed hypothesis test given the above information given a .05 level of significance.

a. Which is the most statistically significant variable? What evidence shows this?

b. Which is the least statistically significant variable? What evidence shows this?

c. For a 0.05 level of significance, should any variable be dropped from this model? Why or why not?
