Suppose the age of buyers were collected and the data follows the bell curve (a normal distribution). The buyers had an average age of 47 years and a standard deviation of 5. The ranges and percentages become

Range Percent Cumulative Pct
32 to 37 2.5 2.5
37 to 42 13.5 16
42 to 47 34 50
47 to 52 34 84
52 to 57 13.5 97.5
57 to 62 2.5 100

1. What is the probability of finding buyers with a value of age greater than 42 years?
2. What is the probability of finding buyers with a value of age less than 52 years?
3. What is the probability of finding buyers with a value of age between 37 and 52 years?
