Review the following regression model which estimates the competitive dynamics of price and advertising. The t$-$values for the estimates are shown in the bracket in italics.

Log $[$Sales $($J&J$)]=$ A $-1\mathrm{.}7(-2\mathrm{.}1)$ Log $[$Price $($J&J$)]+1\mathrm{.}5(+1\mathrm{.}0)$ Log $[$Advertising $($J&J$)]+2\mathrm{.}1(+4\mathrm{.}2)$ Log $[$Price $($Merck$)]0\mathrm{.}8(-2\mathrm{.}4)$ Log $[$Advertising $($Merck$)]$

Merck$$s executives plan that an increase in its $($Merck$$s$)$ advertising by $10$ percent will decrease J&J$$s sales by $8$ percent. TRUE or FALSE? Why? $(2$ points$)$

J&J$$s executives plan that an increase in its $($J&J$$s$)$ advertising of $5$ percent will increase its sales by $7\mathrm{.}5$ percent. TRUE or FALSE? Why? $(2$ points$)$

Merck$$s price has a bigger impact than J&J$$s price on J&J$$s sales. TRUE or FALSE? Why? $(2$ points$)$
