Please help Fast I need to turn this in before 12:20
zhannawk [14.2K]

if you put the points into the equation y2 - y1/x2 - x1 you'll end up with a zero in the denominator, which indicates a vertical slope. Basically the slope(m) is undefined

It's really easy to tell if your answer is going to be undefined if both the x values are the same (in this case they're both 9)

Suppose that the regression for predicting weight (in pounds) from Height (in Select one answer inches) is given by Weight =-115
Nutka1998 [239]

Answer:

Option D)  I and II only                                    

Step-by-step explanation:

We are given the following in the question:

Regression equation:

w = -115 + 3.6h

where w is the weight in pounds and h is the height in inches.

Since the weight depends on height, height becomes the independent variable and weight becomes the dependent variable.

I. A person who is 61 inches tall will weigh 104.6 pounds

When h = 61,

w = -115 + 3.6(61) = 104.6

Thus, the given statement is true.

II. For every additional inch of height, the predicted weight will increase, on average, by 3.6 pounds.

If the height increases by 1 unit, then,

w(h+1) - w(h) = -115 + 3.6(h+1) - (-115 + 3.6(h))\\w(h+1) - w(h)  = 3.6(h+1-h)\\w(h+1) - w(h)  = 3.6

Thus, the given statement is correct.

III. The correlation between weight and height is negative.

No, the given statement is not correct as with increase in height the weight increases and with decrease in height the weight decreases.

Thus, the correct answer is

Option D)  I and II only
