The z-score is given by: Hence, the z-score is equal to 0.046 Part D Hence, P(z - 0.08) = 0.468119 Part E Thus, the average risk making investments is equal to 0.0463 Part I Hence, the risk making investments is equal to 0.8439 Part ii Thus, the risk making investments is equal to 0.8439 Part iii Thus, the risk making investments is equal to 0.8439 Part I Hence

3STATISTICSSection 1Part AFigure 1: Relation of Annual Contribution to IncomeFigure 1 presents the scatter plot of annual contribution to income. The relation betweenincome and annual contribution can be represented as: AnnualContribution=2931+0.1195∗IncomeThus, it can be seen that with increase in income the annual contribution also increases. Part BThus, when income = $200,000, the annual contribution can be estimated as: AnnualContribution=2931+0.1195∗200000=$26,831Part CThe average of the estimate is $27,000. The standard deviation is $2,100. The z-score is given by: z=value−meanstandarddeviation=x−μσ=26831−270002100=−1692100=−0.08Hence, the z-score is -0.08Part DHence, P(z < - 0.08) = 0.468119
