Step 1
Mean of X (X̄) = (75+30+60+80+53+35+15+40+38+48)/10 = 47.4 Mean of Y (Ȳ) = (85+45+54+91+58+63+35+43+45+44)/10 = 56.3 Show more…

For 100 students of a class, the regression equation of marks in Statistics (X) on the marks in Commerce (Y) is 3Y - 5X + 180 = 0. The mean marks in Commerce is 50 and the variance of marks in Statistics is 4/9th of the variance of marks in Commerce. Find the mean marks in Statistics and the coefficient of correlation between marks in the two subjects.

$(a)$ find the equation of the regression line, (b) construct a scatter plot of the data and draw the regression line, (c) construct a residual plot, and $(d)$ determine whether there are any patterns in the residual plot and explain what they suggest about the relationship between the variables. $$\begin{array}{|cc|c|c|c|c|c|c|c|c|} \hline \boldsymbol{x} & 8 & 4 & 15 & 7 & 6 & 3 & 12 & 10 & 5 \\ \hline \boldsymbol{y} & 18 & 11 & 29 & 18 & 14 & 8 & 25 & 20 & 12 \\ \hline \end{array}$$
