Question
A local ice cream shop kept track of the number of cans of cold soda it sold each day, and the temperature that day, for two months during the summer. The data are displayed in the scatterplot below 195 190 185- 180 175 170 165 75 Temperature in degrees Fahrenheit (F) 65 85 95 The one outlier corresponds to a day which was a holiday and the shop had an unusually high volume of customers. Which of the following is true? o If the temperature were measured in degrees Celsius (932),the value of r would change accordingly O A reasonable value of the correlation coefficient r for these data is 1.3. O If the outlier were removed, r would get closer to -1. 0 if the outlier were removed, r would get closer to 1. If the outlier were removed, r would get closer to 0Explanation / Answer
Answer is " If the outlier were removed, r would get closer to 1"
Explanation:
1. If temperature were measured in degrees Celsius ,the value of r would not change
2.correlation coefficient always lies between -1 to 1 ,so correlation can not be 1.3
3. Scatterplot shows strong positive correlation so the value of r can not be 0 or -1
