In March, Maggie collected the daily sales of ice-cream in Montreal (Y) and the outdoor temperature for each day (X). She computed the sample correlation coefficient between X and Y to be 0.1, and used the data to build a simple linear regression model Y = b + cX. Which of the following statements is true? O c in the linear regression mode Y = b + cX is positive O The related coefficient of determination is 0.1 O All of the other answers are true O Only 10% of the variation of the ice-cream sales is explained by different outdoor temperatures. O 90% of the variation of the ice-cream sales is due to the variance of the sales itself
