$1-$ Write the equation for the simple linear regression line in Regression Report #$2$ Identify the y intercept and the slope of that equation

$2-$ Comparing the two simple regressions in Reports $1$ and $2,$ which of the two independent variables $($Pages#$$ or $$Animation$)$ explains$/$accounts

for the most variation in the dependent variable of labor hours? Justify your answer citing the statistic you use to make the comparison.

$3-$ Using Regression Report #$1,$ how many labor hours are needed to create an e$-$learning module with $500$ pages?

$4-$ In Regression Report #$3,$ is there a significant linear relationship between the independent variable $$Animation$$ and the dependent variable $$Labor hours$$ in the true population? Justify your answer based on both tests of significance$/$linearity $($p value and confidence interval$)$

$5-$ In Regression Report #$3,$ Is the effect of Animation gross or net with respect to Pages#$?$ What is the value of this effect?
