Suppose 190 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 85 g and standard deviation 1g. Use the symmetry of the normal curve and the empirical rule as needed to estimate the number of students reporting readings between 84 g and 86 g. The number of students reporting readings between 84 g and 86 g is (Round to the nearest whole number as needed)
