when the value of X is . . Find the line regression of Y on X Y . Using the following information you are requested to (i) obtain the linear regression of Y on X (ii) Estimate the level of defective parts delivered when dx inspection expenditure amounts to ` ∑ X = , ∑ Y = , ∑ X =21926, ∑ Y =15123, ∑ XY =12815, N = .
Here X is the expenditure on inspection, Y is the defective parts delivered. . The following information is given. Details X (in ` ) Y (in ` ) Arithmetic Mean Standard Deviation Coefficient of correlation between X and Y is .
Find (i) The regression Coefficient of Y on X (ii) The most likely value of Y when X = ` .
