Homework - Due Day Monday Nov 16
The table below presents the temperature and ice cream sales data for 5 days (Modified from Weinberg and Abramowitz)
Ice Cream Bars and Temperature Data
| TEMP in Fahrenheit | BARSOLD |
| 75 | 170 |
| 70 | 160 |
| 65 | 155 |
| 60 | 150 |
| 72 | 153 |
The linear regression formula to predict the number of ice cream bars that will be sold based on the temperature is
BARSOLD = 1.18*TEMP + 75.78
