Solve the below problem:
Q: Bleep tests are used to measure people's fitness. A higher score means a higher level of fitness. The heart rate, p beats per minute, and bleep score, s, for 12 people were recorded and coded, using x = p - 60 and y = 10s - 50. x 0 -6 9 -1 5 8 30 19 28 20 36 23 y 55 62 38 -7 50 44 8 8 3 20 -14 3 S x = 171, S y = 270, S x 2 = 4477, S y 2 = 13540, S xy = 1020.
(a) Find the PMCC between x and y.
(b) Write down the PMCC between p and s.
(c) Explain why your answer to(b) might suggest that there is a linear relationship between p and s.
(d) Interpret the significance of the PMCC.
