Answer:
And the slope would be:
Now 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:
And the best option is:
A. y = 0.894x + 0.535
Step-by-step explanation:
We have the following dataset given
x: 5,6,9,10,14
y: 4,6,9,11,12
We want to find the least-squares line appropriate for this data given by this general expresion:
Where m is the slope and b the intercept
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:
And the best option is:
A. y = 0.894x + 0.535
