Answer:
Nowe we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:
C. = 1.45 + 0.074x
Step-by-step explanation:
The data given is:
x: 5,5,510,10,10, 15,15,15, 20,20,20
y: 1.6,2.2,1.4, 1.9, 2.4,2.6, 2.3,2.7, 2.8,2.6, 2.9, 3.1
For this case we need to calculate the slope with the following formula:
Where:
So we can find the sums like this:
With these we can find the sums:
And the slope would be:
Nowe we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:
C. = 1.45 + 0.074x
