An electronics retailer would like to investigate the relationship between the selling price of a digital camera and the demand for it. The table shown below gives the weekly demand for the camera in one particular
market along with the corresponding price. These data have a sample correlation coefficient, rounded to three decimal places, of -0.852. Using a = 0.01, test if the population correlation coefficient between the
selling price and the demand for the camera is less than zero. What conclusions can you draw?
