A coffee shop owner is interested in comparing the average spending of rich, poor and middle class clients on coffee. Assume that the populations are independent and they follow the normal probability distribution. Further, assume that the population standard deviations are known. The appropriate test statistics for simultaneously comparing the average spending of rich, poor and middle class clients on coffee is * a. T- statistics b. Z-statistics c. Both a and b d. None of these
