SECTION 1A.SCATTERPLOT SHOWNB.The regression line is Annual C = -2153 +0.13*Income. So if income is 200000 then predicted annual contribution = -2153 +.13*200000 = $23847. C.Z score = ( 23847-27000)/2100 = -1.501D.P( z <-1.501) = 0.0666E.Expected rank = 0.0666 * 10000 = 666.

Section 2A.p1 = 0.176 , n1 = 68; n2 = 32 and p2 = 0.125. B.the graph is below for sample size and risk separately:C.The probability of a making a loss on risky investment is 0.176. the probability of making a losson safe investments is lower at 0.125. D.i.Using the values p1-p2 = 0.0514ii.Z score = ( 0.0514 -0.1)/0.0743 = -0.653iii.P(z < -0.653) = 0.2568iv.Expected rank = 4000 *.2568 = 1027.3 or 1028 after rounding off.E.i.Ho: p1-p2 = 0H1: p1 - p2 ≠ 0ii.p value = 2*P( z < -.653) = 0.513 ( we multiply with 2 as this is a 2 tail test)iii. as the level of significance is 0.05 we compare p value with 0.05. p value > 0.05 so we DO NOT REJECT the null hypothesis.
