Given the following null and alternative hypotheses:
H0:
σ₲ ≤ σ₂²
Ha:
σ₲ > σ₂²
and the following sample information:
Company X
Company Y
n = 32
n = 42
S₲ = 195.89
S₂² = 87
So, the calculated test statistic will equal:
Question 2
If you want to test whether sample #1 has a lower standard deviation than Sample #2, then you will state the hypotheses as following:
