Consider once more the equation:  y = ß0 + ß1x + ε . If we computed this on sample data, then when xi = 0, the predicted value for y would be:   a) 0 b) the mean of y c) whatever ε is equal to for the given problem d) ß0 e) a necessarily positive intercept

11.) Suppose y varies directly with x. If x is -7 when y is 3, what is x when y is -5? a. -11 2/3 b. -4 1/5 c. 4 1/5 d. 11 2/3

5.) Use the table below to:a. Calculate the absolute risk of food poisoning among those who ate fish and those who did not eat fish b. Calculate the relative risk of food poisoning among those who ate fish comparedto those who did not eat fish    food poisoning no food poisoning ate fish 23 89 did not eat fish 45 167

The formula for the best fit line is y= -72359.6+216.2x, where y is sales price and x is square footage of the house. One house in this data set has 3,140 square feet of living space and sold for $485,000. Calculate the residual of this data point: a) -16859.6 b)16859.6 c)-121384.26 d)121384.26 e)none of the above

A) Y=1566.67x + 1716.67 B) Y= 3x + 2000 C) Y= 4700x + 1500 D) Y= x + 1700
