The weight of a car can influence the mileage that the car can obtain. A random sample of 19 cars was taken and the weight (in pounds) and mileage (in mpg) were recorded and are in the table below.

X, weight	Y, mileage
4500	19.5
3000	32.2
3500	28
3500	31.3
4500	17.2
4000	23.4
4000	23.6
3000	32.2
2500	40.9
3500	28
5500	13.2
2250	41.1
3000	31.4
4000	23.6
2750	46.9
3500	28
4000	23.1
4500	17
3500	32.6

a) The symbol and value of the correlation coefficient are as follows:

Round final answer to 2 decimal places.

Select an answer r R² ρ ŷ y p̂ X̄ p μ σ s =

Interpret this value:

There is a strong Select an answer positive negative Select an answer linear quadratic bell-shaped uniform relation between weight and mileage for cars.

b) The symbol and value of the coefficient of determination are as follows:

Round final answer to 2 decimal places.

Select an answer r r² ρ ŷ y p̂ X̄ p μ σ =

Interpret this value:

About % of the Select an answer mean mileage variation in mileage mean weight variation in weight Select an answer can be cannot be explained by the linear model on weight
