    See table below. Determine the regression line of y on x if it is already known that the averages are 6.50 and 8.75, and the correlation between x and y is 0.52.


    1. FALSE: ŷ=0.50+5.50x\hat{y} = 0.50+5.50x
    2. FALSE: ŷ=1.73+0.55x\hat{y} = 1.73+0.55x
    3. FALSE: ŷ=0.55+1.73x\hat{y} = 0.55+1.73x
    4. TRUE: ŷ=5.50+0.50x\hat{y} = 5.50+0.50x
