I am having a hard time figuring this out.
The null and alternative hypotheses are:
HO: The cell categories are equal.
H1: The cell categories are not equal.

Compute the value of chi-square.
-----------------
The numbers you have for A,B,C etc. are the "observed" data values.
The "expected" data values would be 20,20,20,20 since there are
80 data points and four categories.
---
List the "observed" values in one set.
List the expected values in another set.
Run a Chi-Sq Goodness-of-Fit test on the two sets.
---
I did and got:
Chi-Sq = 10
p-value = 0.1886
---
Conclusion: Since the p-value is greater than 5%
fail to reject Ho.
