QUESTION 2 · 0/1 POINTS
Which of the following are feasible equations of a least squares regression line for number of dollars left in an endowment
providing college scholarships in each of its first ten years if it was entirely funded by a single donation?
X
That's not right.
O
y = 269,000 + 83003
O
= 69, 000 – 83003
O
y = –269,000 - 8300.0
O
= 269,000 - 83000
O
j = 0 - 83002

(B) y = 69,000 - 8,300x

Step-by-step explanation:

Let 8,300 be the scholarship and y be the remaining amount. Also x is the number of years.

Each year, the amount 8,300 is reduced by giving the scholarship worth 8,300. Hence, the coefficient of x should be negative sign.

If the initial amount is 69,000 and the remaining amount after 10 years is negative, the regression equation is

y = 69,000 - 8,300x

2t+4

step-by-step explanation:

a. the residual plot for model 1 has a random pattern and is a good fit for the data.
