Consider the following Hypothesis Testing:

H0: &#948;1² = &#948;2²
Ha: &#948;1² &#8800; &#948;2²

The sample size for sample 1 is 25, and for sample 2 are 21. The variance for sample 1 is 4.0 and for sample 2 is 8.2

a) at the confidence level of 0.98, what is your conclusion of this test?
b) What is the confidence interval for the ratio of &#948;1/&#948;2, of which the Null Hypothesis is True?
