Testing for mean equality between the salary and compa-ratio values for each employee in our case study example
would use the
t-test assuming equal variance
t-test not assuming equal variance
paired t-test
we cannot compare these two measures.
Answer: Salary and compa-ratio are two different variable, with different units of measurement. Therefore, we cannot compare these two measures using the given tests.
Hence the option:
We cannot compare these two measures is correct option.
