UploadUS crimedata, make a chart with x-axis being the robbery in Vermont andy-axis being the robbery in Connecticut. Answer the questions:
I) Plot the chart and fitted line. What is the interpretation of the slope?(11.11 points)
a. It predicts the number of robberies in Connecticut when there are no robberies in Vermont.
b. It predicts the number of robberies in Vermont when there are no robberies in Connecticut.
c. It predicts the increase in number of robberies in Connecticut for each additional robbery in Vermont.
d. It predicts the increase in number of robberies in Vermont for each additional robbery in Connecticut.
e. None of these.
II) The fitted line exhibits a positive slope.Is this expected or not, and why? (11.11 points)

b. Yes this is expected, since slope is positive.
c. Yes, it is expected since R-square is very good.
