There are six hundred cabs in Kingston. The odometer reading in each cab is not normally distributed, but is known to have a mean of 67,000 km. You collected a sample of 45 cabs and found a sample mean of 68,500 km and a sample standard deviation of 8,000 km. What is the probability, to four decimal points (eg a number like 0.1234), that your sample can have a sample mean greater than 68,500 km? 6/
