Answer: 30. If you assume that the 600 lenses tested come from a population with a normal distribution (which they do), you can apply the empirical rule (also known as the 68-95-99.7 rule). Using the empirical rule, approximately 95% of the data lies within two standard deviations of the mean, and 5% of the data lies outside this range. Beyond biology, the book connects to the broader context of data science emerging within many academic disciplines and throughout modern life.
