Answer:
We can predict the sales representative travelled 8 miles replacing x =8 and we got:
And we can predict the sales representative travelled 11 miles replacing x =11 and we got:
Step-by-step explanation:
For this case we have 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
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:
We can predict the sales representative travelled 8 miles replacing x =8 and we got:
And we can predict the sales representative travelled 11 miles replacing x =11 and we got:
