Problem Statement

Write a function to determine whether a given set of frequency counts could plausibly have come from a uniform distribution by using the

χ

2

{\displaystyle \chi ^{2}}

test with a significance level of 5%.
The function should return a boolean that is true if and only if the distribution is one that a uniform distribution (with appropriate number of degrees of freedom) may be expected to produce. Note: normally a two-tailed test would be used for this kind of problem.

Let's start with the solution:
