Suppose 120 geology students measure the mass of an ore sample. Due to human error and limitations in the reliability of the balance, not all the readings are equal. The results are found to closely approximate a normal curve, with mean 87 g and standard deviation 1 g. Use the symmetry of the normal curve and the empirical rule as needed to estimate the number of students reporting readings more than 87 g. Click here to see page 1 of the table for areas under the standard normal curve, Click here to see page 2 of the table for areas under the standard normal curve. The number of students reporting readings more than 87 g is (Round to the nearest whole number as needed.)
