Suppose 140 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 82 g and standard deviation 3 g. use the symmetry of the normal curve and the empirical rule as needed to estimate the number of students reporting readings between 76 g and 88 g.

it would take 7/10 of an hour too fill the pool.
