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
Ok pretty sure the probability of a 5 is 1/5
The probability of a # greater than 3 is 2/5
And the probability of a 2 or 5 is 2/5
(1/5 is 20% and 2/5 is 40% if you need those)
Answer:
so the first one unselect
the second one check it
the third one unselect
the fourth one check it
the fifth one check it
The answer is going 5 - 2x = 3
