✒ Answer
Answer:
Step-by-step explanation:
We assume that th data is this one:
x: 50, 55, 50, 79, 44, 37, 70, 45, 49
y: 152, 48, 22, 35, 43, 171, 13, 185, 25
a) Compute the equation of the least-squares regression line. (Round your numerical values to five decimal places.)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:
