Consider the observed frequency distribution for the following set of random variables:

Random Variable, x              Frequency, fo

0 ………………………………         17

1 ………………………………         35

2 ………………………………         30

3 ………………………………         15

4 and more …………………….         3

Total ……………………………       100

Perform a chisquare test using α = 0.05 to determine if the observed frequencies follow the Poisson probability distribution when λ = 1.5.
