FAN AND MEDAL
Can you definitely say if any of the choices are true or not ?
Do you see the 72 at the bottom? put your finger on the 72 and move straight up until you reach the orange line. then move sideways to the left. what number are you at (on the y-axis) ?
you should be between 10 and 11 (at 10.5) The orange line is the prediction, and the "dots" are what was measured. I would say the line is "close" to the dots, so it gives "close" predictions. I would say choice A is not true (don't pick it)
I'm not sure about the 2nd line, the prediction is an interpolation. This might be true, but it depends on what they mean or have taught you. I would guess the 2nd line is true, but who knows what they want.
when you moved your finger up from 72 to the orange line, did you find a dot on the orange line ?
no, there is no black dot on the orange line at 72,10.5 It looks like there is a dot at 71, 10.5 if I'm reading it correctly. But there is no dot at exactly 72,10.5 what does that mean for statement C (3rd statement) ?
the statement says No data at 72 There is no black dot at 72, so that part is true the statement also says the shoe size can be predicted Is that true? can we predict the shoe size for 72 ?
yes, we use the orange line to predict the shoe size is 10.5 that means the 3rd statement is true.
the last line is definitely not true the 2nd to last line is probably true, but I am not sure We definitely use the linear regression line to make a prediction, but without it, we could guess the answer is near the other dots near 72. So I would guess it's true
