Question

The publisher of a new magazine gathered data from potential subscribers about their age and the price they would be willing to pay a for a 2-year subscription. He used a graphing tool to organize the data in a scatter plot and find the line of best fit. He found that the relationship between a person’s age, x, and the price, y, is modeled by the equation y = 0.981x − 1.714, and the correlation coefficient for the data is 0.237. Could this line of best fit be used to make reliable predictions about the price a potential subscriber is willing to pay?

Answer 1

Answer:No, because the correlation coefficient is closer to 0 than to 1 , which indicates a weak association between the variables
