A random sample of 12 winter days in Denver gave a sample mean pollution index of 43. Previous studies show that the population standard deviation is 21. For Englewood, a random sample of 14 winter days gave a pollution index of 36. Previous studies show that the population standard deviation is 15. Assume the pollution index is normally distributed in both Englewood and Denver. What formula would you use to calculate the test statistic?
