Predicting values from the equation for the Linear Regression line.

Questions and Answers
• 1.

### The data set above (Data Set 8) shows the height (x) and weight (y) of a team of soccer players.Using the linear regression line, what is the predicted weight to the nearest kg for the player who is 161cm tall?

Explanation
Find the equation for the line for the linear regression for the data set. This will give you the value for 'a' and 'b', which can then be used in the App bivarequ2predict. If you have an existing value, it will also find out the residual for you.
