Answer to Problem 4PPS
Explanation of Solution
Given information:
The table shows the number of field goals and assists for some of the members of the Miami Heat in a recent NBA season.
Make a
Calculation:
The slope of the line is positive and the points are close to the line.
The slope of the line is negative and the points are not close to the line.
No correlation:
There is no obvious pattern of increase or decrease for the given data.
Consider the table provided into textbook.
Graph the data as ordered pairs with the field Goals on the horizontal axis and the assists on the vertical axis. Draw a line through two points that appear to represent the data well, such as
Use maple to graph a scatter plot and a line of fit.
Suppose
The data show a weak positive correlation.
b.
Use two ordered pairs to write a prediction equation.
