Jasmine compared the two graphs below. Graph A Daily High Temperatures and Bottled Water Sales Graph A has temperature (degrees

Fahrenheit) on the x-axis and Number of bottles sold on the y-axis. Points are grouped together in a line with positive slope. Graph B Daily High Temperatures and Bottled Water Sales Graph A has temperature (degrees Fahrenheit) on the x-axis and Number of bottles sold on the y-axis. Points are grouped together and increase. A few points are outside of the group. She decide to use graph A to predict the number of bottles of water that would be sold when the temperature is 100 degrees Fahrenheit. Which is likely Jasmine’s reasoning? Graph A has a stronger correlation, so it is more likely to provide an accurate prediction. Graph A has a temperature reading of 90 degrees, which is closer to 100 degrees. Graph B has a negative correlation, so it would not be suitable. Graph B has a strong correlation, but it has an outlier.
