Q3) Since the pvalue is small, the slope is significant. Thus, the effect of number of bedrooms on house price is significant.
Ans: Option 4
Q4) R-squared (R2) is a statistical measure that represents the proportion of the variance for a dependent variable(price of house) that's explained by an independent variable(number of bedrooms) or variables in a regression model.

QUESTION 13 For a simple linear regression model, the estimated intercept is 5, and the estimated slope is -3, it implies that as the independent variable increases by 1 unit, the dependent variable would increase by 5 units. as the independent variable increases by 1 unit, the dependent variable would decrease by 3 units. as the dependent variable increases by 1 unit, the independent variable would increase by 5 units. as the dependent variable increases by 1 unit, the independent...
