4.2 Scatter Diagrams and Correlation 1. An ice cream shop keeps track of how much ice cream they sell versus the high temperature for the day. Here is their data for 12 days. Make a scatter diagram to represent the data. correlation ( x, 4)= 0.9575 Ice Cream Sales vs Temperature Temperature .C Ice Cream Sales X A 2 YAZ x * y 14.20 $215 201. 209 /46225 3053 16.40 $325 268.

Your scatter diagram on the previous page should have looked like there is a strong linear correlation. Go back and use a ruler to draw an estimated least squares regression line (also known as a "line of best fit."). Don't do any math for this, just put the ruler on the dots and draw the line that looks the best to you. It will help you answer the next question if you make sure your line goes through at least two of the dots. 2. What is the slope of the line you drew? Use the slope formula m = 12 1. Interpret the X2 -X1 slope in the context of the example
