Upload the ManBody data. Create a scattered plot chart with X representing the Age and Y representing BodyFat. Plot the regression line and compute the R-squared. Answer the questions:
I) There is an outlier present: a person with zero body fat. What is his age?
a. Between 50 and 75
b. Between 70 and 80
c. Between 30 and 35
d. Between 35 and 45
e. None of the above
II) Remove the outlier discussed in question I. To do so, find the actual data point in the list and delete the X and Y coordinates. Redo the chart but now without this outlier. What is the approximate slope?
a. 0.4771
b. 0.0853
c. 0.1788
d. 10.933
e. None of the above
III) What is the approximate Y-intercept for the chart without the outlier?
a. 0.4771
b. 0.0853
c. 0.1788
d. 35.852
e. None of the above
