$$

Fill in the blanks in the following.

$25\mathrm{.}2-25=$

$($b$)$ Using the OVB formulae we worked on in the Week $10$ lecture notes, the difference between the coefficient on $R$ in Eq $(1)$ and $(6)$ equals to

$23\mathrm{.}4-25=$

To minimize canvas grading issues in this question, PLEASE:

$($i$)$ input exact values for the coefficient given above, e$.$g$.$ do not omit the zero to the left of the decimal point from values smaller than $1$

$($ii$)$ follow the order of the terms in the OVB formula given in class,

$($iii$)$ In Part b$,$ follow the order of the variables in the regression.
