Answer:
And for 0 miles if we use the model we got:
But for this case. No is not reasonable for a representative to travel o miles and have a positive amount of sales.
Step-by-step explanation:
For this case we assume the following data:
Miles traveled (X): 2,3,10,7,8,15,3,1,11
Sales (Y): 31,33,78,62,65,61,48,55,120
We want to found a linear model like this one : . Where:
Where:
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 for 0 miles if we use the model we got:
But for this case. No is not reasonable for a representative to travel o miles and have a positive amount of sales.
