Given : Julia goes bowling, her scores are normally distributed with a mean of 200 and a standard deviation of 14.
To Find : Using the empirical rule, what percentage of the games that Julia bowls does she score between 158 and 242
Solution:
Mean = 200
she score between 158 and 242
(158 - 200)/14 = - 3
(242 - 200)/14 = 3
Hence her score lies with in - 3SD to + 3SD
As per empirical rule
100 % data lies with in - 3SD to + 3SD
Hence she will score 100 % between 158 and 242
