5. True or False: [6C]
a) The correlation coefficient will always be positive when the slope of the line of best fit is positive. Explain your reasoning.
b) Two lines of best fit have these equations: Line A: y = 1.5 x + 2 Line B: y = 6x - 1
Joe says that line B has a stronger correlation since it has a greater slope. Explain.
c) Merner’s golf drives have a mean distance of 245 m with a standard deviation of 35 m, while Phillip’s golf drives have a mean distance of 215 m with a standard deviation of 15 m.
Merner is a better golfer than Philips since he is more consistent and has a higher average drive distance
