Given are five observations for two variables, & and . i 50 40 52 a. Choose the correct scatter diagram for these data: '.J_. - l 60+ G0 v S0+ s S0 40+ 40 30+ a0 20t 20 " 1 10+ 10 . } } | | | } } | } | b | 1 10 20 a0 40 50 &0 10 20 a0 40 S0 80 C. b G0+ [518] T * S0+ 50 A0+ & A0 o 0T+ 30 204 e 20 e 12 21 60 604 50 & S0+ & 40 40+ a0 0+ 20 s 204 s .

There appears to be a |W| linear relaticnship between & and . c. Try to approximate the relationship between @ and y by drawing a straight line through the data. |m| to provide a linear approximation of the relationship between & and . d. Develop the estimated regression equation by computing the values of by and by using equations: (Enter negative values as negative figure) 3 (@i 7)(wi 7) b= Z{mi - &) by =7 T = - * (to 2 decimals) e. Use the estimated regression equation to predict the value of y when = 6, = (to 2 decimals) 2y
