Question 6 [Total 2.5 points] Oncotype DX is a genomic score measured in breast cancer patients and used to make treatment decisions. Oncotype DX score takes values between 0 and 100. Oncologists want to examine the effect of the expression of NG, a new breast cancer gene, on Oncotype DX. Therefore, oncologists recruited a random sample of 50 breast cancer patients, measured their expression of NG and their Oncotype DX score, and performed a simple linear regression analysis. Plots and SPSS output of the regression analysis for this study are given below. Answer the questions given below: 10 12 00 ONCOTYPE DX FREQUENCY J O 70 75 80 85 6 8 10 12 14 ONCOTYPE DX NG EXPRESSION Coefficients Standardized Unstandardized Coefficients Coefficients Model B Std.
