QUESTION 1

(a) r = 0.91,strong positive correlation/relationship

(b) Participation in support programs will lead to good marks in the examination

(c) common variance = r² x 100

= 0.91² X 100 = 82.81%
(d) a = Y – bX
= 2.93 – 0.81(3)
= 0.5
(e) Y = bX + a
For x =1
= 0.81(1) + 0.5
= 1.31
=1
For x =9
= 0.81(9) + 0.5
= 7.79
=8
