A scientist found that the lengths of a certain population of snakes can be reasonably described using a normal distribution with a mean of 42 cm and a standard deviation of 2 cm. If the scientist collected a sample of 89 snakes, how many of the snakes would be expected to have a length less than 40 cm? A 14 30 C 60 D 74
Every year, the students at a school are given a musical aptitude test that rates them from 0 (no musical aptitude) to 5 (high musical aptitude).
