I need help with this question, and I need you to break it down to me like I am a 5 year old if possible. I have part of the equation done, but I am stuck, and I also want to make sure what I have done so far is correct. Thank you in advance!

Each of the following pairs represents the number of licensed drivers (X) and the number of cars (Y) for seven houses in my neighborhood:

Drivers (X) Cars (Y)

5 4

5 3

2 2

2 2

3 2

1 1

2 2

(b).Determine the least squares equation for these data.(Remember, you will first have to calculate r, SS_y , and SS_x).

n= 7X = 20Mean = 2.8571Y= 16Mean = 2.2857XY= 54 X²= 72 Y²= 42

SP_XY = XY- (X) (Y) n54- (20)(16)7=8.2857

SS_X = X² - (X)² n 72 - (20)² 7 = 14.8571

SS_Y = Y² - (Y)² n42 - (16)² 7= 5.4286

8.2857 8.9807= 0.9228

r= 0.9228

SS_X= 14.8571

SS_Y= 5.4286

Y' = bX + a

2.29 - (0.1447)(2.8571)=1.8723

b= 0.1447

a= 1.8723

Y' = bX + a=Y'= 0.1447 x

(c).Determine the standard error of estimate S_y/x, given that n= 7.

(d).Predict the number of cars for each of two new families with two and five drivers.
