Question
As part of the first-year evaluation for new salespeople, Ada, the sales manager for Umbrella, estimates the second-year sales for each salesperson based on his or her sales for the first year. Using data from company records going back several years, she constructs the following scatter plot:

a). Indicate a range of plausible values for the correlation between first- and second-year sales. Note: The acceptable answers are based solely on what you know about the concept of correlation; you need not calculate anything for this part.
b). Ada fits the least-squares line y = 18.22 + 1.66x where x = first-year sales and y is second-year sales. Interpret both the slope and the y-intercept in the context of the problem of estimating second-year sales.
c). What is a potential problem, from your perspective, with using the least-squares line to estimate sales and evaluate employees?
Summary
The question belongs to Statistics and it discusses about the plausible values for correlation between first and second year sales given in the scatter plot.

HwA turned me into a chemistry lover from a chemistry hater. It was in my final years of my high school when I first took their help with my chemical compounds assignments and how I am doing my B.E. in Chemical Engineering and still taking their help in the matter.
All the curves used to confuse me a lot. I was not getting any direction while all of my classmates were cruising through their Monopoly, Oligopoly market equilibrium assignments. Then my friend Judith introduced me to HwA and then I felt much better after taking their economics homework help. They helped me understand and also get good marks.
The accounting tutors here can surely make the numbers talk. In my freshmen year, I was unable to understand what to put under assets and what under liabilities. It was back then I took their help and also helped me understand why “capital investment†is a liability to the business. I am doing my Masters now and still take their help.
I totally loved getting helped from a Melbourne based tutor via HwA as I believe someone from UK or the States could have understood the specifications required for my assignment. It is a marvellous website and I encourage all my fellow students from Melbourne to avail help from HwA as and when they need.
I really needed assistance with my clinical epidemiology assignment while I came across HwA and was thrilled to find that they have expert dealing with that area of nursing. It was really cherishing and the nursing experts here are well experienced and well equipped with the nitty-gritty of a patient care.

Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
