The regression equation of Y on X is given by the following formula:

Where byx is given by the formula:

Where N is the number of values (N=8). We need to find the sum of X values, the sum of Y values, the average of X, the average of Y, the sum of X*Y and the sum of X^2.
The table of values is:
The values we need to know are on the following table:
By replacing the known values in the formula we obtain:

Now, the average of X and Y is the sum divided by N, then:

Replace these values in the formula and find the regression equation as follows:

The answer is a) y=4.6x+28.26
Y=2x-6 (4, 3)
(X, Y)
3=2(4)+b
3=8+b
-5=b
Y=2x-5
4/1 is the same as 4.
So 4+3/4= 4 and 3/4
<u>Final Answer</u>= 4 and 3/4
Answer:
2^2×20
Step-by-step explanation:
2^2×20
because 2×20=40
so, 2^2×20=2^40
Answer:
