Question

Go to the Subset tab, which gives a subset of randomly chosen data from the first tab. Go to your Math Tools and open the Graph tool. Plot the data of weight (carat) versus price in this tab using the +Data button (Note that you can copy two columns of data and use "paste table data"). Export an image of the plot, and paste it in the space below. Find the equation of the regression line (using a Best Fit Linear relationship) and the value of the correlation coefficient (r).

Answer 1

A linear regression model is used to show the relationship between variables on a scatter plot

The equation of the linear regression model is: $\^y = 1.56\^x + 1.29$ and the correlation coefficient is 0.8034

How to determine the equation of the linear regression

The question is incomplete. So, I will make use of a dataset that has the following calculation summary (from a graphing calculator)

• Sum of X = 45
• Sum of Y = 83
• Mean X = 4.5
• Mean Y = 8.3
• Sum of squares (SSX) = 82.5
• Sum of products (SP) = 128.5
• The value of R is 0.8034.

The equation of the linear regression model is:

$\^y = 1.56\^x + 1.29$
