(In this problem first find the probability by using SPSS and then calculate the number of trees manually by using the probabilities.)

A certain variety of pine tree has a mean trunk diameter of μ=150 cm, and a standard deviation of σ=30 cm which is normally distributed. A certain section of a forest has 500 of these trees.

Find Approximately

1. how many of these trees have a diameter smaller than 120

2. how many of these trees have a diameter greater than 160

3. how many of these trees have a diameter between 130 and 160.

4. how many of these trees have a diameter between 120 and 140.
