a. Construct a scatterplot. Choose the correct graph below. x y 10 9.15 8 8.15 13 8.74 9 8.77 11 9.25 14 8.11 6 6.13 4 3.11 12 9.13 7 7.27 5 4.74 . Find the linear correlation​ coefficient, r, then determine whether there is sufficient evidence to support the claim of a linear correlation between the two variables. Using the linear correlation coefficient found in the previous​ step, determine whether there is sufficient evidence to support the claim of a linear correlation between the two variables. Choose the correct answer below. Identify the feature of the data that would be missed if part​ (b) was completed without constructing the scatterplot. Choose the correct answer below.

Answer IN R CODE please. Using the data below, Create a scatterplot of y vs x (show this) and fit it a simple linear regression model using y as the response and plot the regression line (with the data). Show this as well. Test whether x is a significant predictor and create a 95% CI around the slope coefficient. What does the coefficient of determinations represent? For x=20, create a CI for E(Y|X=20). Show this. For x=150, can you use...
