Answer
The requirements are:
- No expected counts must be equal or greater than 1, that is $E_i\geq1$
- The proportion of expected counts that are less than 5 can not be greater than 0.2 (20%)
The given values are the observed counts, not the expected counts. The expected counts will be given in part (d).
Work Step by Step
Altough there are 2 observed number of regions equal to 0 and the proportion of observed counts, $\frac{3}{8}=0.375$, that are less than 5 is more 0.2, it is not a violation of the requirements for conducting a goodness-of-fit test.
