Find the probability that a data value picked at random from a normally distributed population will have a standard score that corresponds to the following less than 3.00

The empirical rule says that approximately 99.7% of any normal distributions falls within three standard deviations of the mean, which leaves 0.3% outside that range, and due to the distribution's symmetry, 0.15% to either side. This means




So



or about 99.9%.
