12)Researchers used the least-squares method to study the relationship between the length of time (in munues) a commercial was shown during a week and the number of products purchased. As one of the researchers, use the simple linear regresssion equation to find the predicted number of products purchased if the commercial is shown for 17.35 during the next week. It is known that the y-intercept of the estimated regression line is 24.93, the slope of the estimated regression line is 3.59.Round your answer to 2 decimals (do not round to a whole number, if the answer is not a whole number).
