Suppose that scores on a test are normally distributed with a mean of 80 and a standard deviation of 8. You have been asked to find the 70th percentile. After sketching a standard normal curve and shading the area of interest, the next step in solving this problem is to use the table of areas. Would you look for 0.7 in the body of the table or in the left-hand column? Explain your reasoning.
