The weight of a group of 500 men is normally distributed with a mean of 76 kg and a standard deviation of 5 kg. Calculate the percentage of men weighing between 72 and 80 kg (round to 1 decimal place).
The empirical rule is a statistical rule which states that for a normal distribution, almost all data will fall within three standard deviations of the mean. Broken down, the empirical rule shows that 68% will fall within the first standard deviation, 95% within the first two standard deviations, and 99.7% will fall within the first three standard deviations of the distribution’s mean.
