Question 1195796: 11.An investigator wants to know the relationship between the car’s distance and the sales price. Data were collected on the distance of the cars traveled and the sale price for 10 private sales of model year 2000.
Miles (1000s) Price ($1000s)
90 7
59 7.5
66 6.6
87 7.2
90 7
106 5.4
94 6.4
57 7
138 5.1
87 7.5
Required:
a)Develop a scatter diagram with miles as the independent variable.
b)Use the least squares method to develop the estimated regression equation.

You can put this solution on YOUR website!
.

(1)  A scatter diagram is a graph in which the values of two variables 
     are plotted along two axes.


     So, you can make the scatter diagram on your own, isn't it ?


     You do not need the tutor's help for it . . . 



(2)  To develop the estimated regression equation, go to web-site

     https://www.socscistatistics.com/tests/regression/default.aspx


     Use online calculator, specially created for such purposes - it is free of charge.


     On the way, parallel with using this calculator, learn the relevant theory 
     from the same web-site.


     In the Internet, there are tens of similar free of charge calculators
     with full description of the relevant theory,

     so you can learn it from there, if you still do not know it now.
