Solve the below:
Q: Consider the following Hypothesis Testing:
H0: δ1² = δ2²
Ha: δ1² ≠ δ2²
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 δ1/δ2, of which the Null Hypothesis is True?
