Step 1

The linear model obtained using scatter diagram is given below:

The line that best fits the data is least-squares regression line.

The procedure to draw scatterplot using EXCEL is as follows.

• Select the data Number of Pages (x) and Cost(y).
• Go to Insert.
• Select Scatter under Charts.
• Right click on the obtained chart, check linear, Display Equation on chart.

The scatter diagram for the data that is obtained using EXCEL is as follows: help_outlineImage TranscriptioncloseScatter plot for Cost (y) vs number of pages (x) 120 y 0.1146x+9.55 100 60 Cost (y) 40 Linear (Cost (y) 20 0 200 400 600 800 1000 Number of pages (x) 80 (A) as0 fullscreen
