In a multiple regression, the following sample regression equation is obtained: y-157 + 11.0x1 + 2.3x2 a. Predict y if x1 equals 17 and x2 equals 43. (Round your answer to 1 decimal place.) b. Interpret the slope coefficient of x1. As x1 increases by one unit, y is predicted to increase by 11.0 units, holding x2 constant. As x1 increases by one unit, y is predicted to increase by 2.3 units, holding x2 constant O As x1 increases by...

A regression model between sales (y in $1000), unit price (x1 in 100 dollars), and television advertisement (x2 in dollars) resulted in the following function: ŷ = 7 - 3x1 + 5x2 The coefficient of the unit price indicates that if the unit price is: increased by $100 and holding advertisement constant, sales are expected to decrease by $3. decreased by $1000 and holding advertisement constant, sales are expected to decrease by $3. increased by $100 and holding advertisement constant,...

The interpretation of the slope coefficient in the model Y;= 34.5+ 53.2 In(X) + u; is as follows: O A 1% increase in X is associated with a 53.2% increase in Y. O A 1% increase in X is associated with a 53.2 unit increase in Y. O A 1% increase in X is associated with a 0.532 unit increase in Y. O A 1% increase in X is associated with a 0.532% increase in...
