![**Hypothesis Testing Problem**
**Incorrect.**
Consider the hypothesis test \( H_0 : \sigma_1^2 = \sigma_2^2 \) against \( H_1 : \sigma_1^2 < \sigma_2^2 \). Suppose that the sample sizes are \( n_1 = 7 \) and \( n_2 = 13 \) and that \( s_1^2 = 23.0 \) and \( s_2^2 = 28.9 \). Use \( \alpha = 0.05 \).
(a) Test the hypothesis.
\( H_0 \) [dropdown menu with option 'is not'] rejected.
(b) Find a 95% confidence interval on \( \sigma_1^2 / \sigma_2^2 \). Round your answer to two decimal places (e.g., 98.76).
