Problem

Using 3 The Chi-Square Distribution Table, $\sigma^{2}=225, \alpha=0.10, n=23$, and a two-tailed test, find the following: Part: $0 / 3$ Part 1 of 3 (a) State the hypotheses

Solution

Step 1 :The question is asking for the hypotheses for a two-tailed test. In a two-tailed test, we are testing for the possibility of the relationship in both directions.

Step 2 :The null hypothesis (H0) is that the population variance is equal to the given variance.

Step 3 :The alternative hypothesis (H1) is that the population variance is not equal to the given variance.

Step 4 :The null hypothesis, \(H_{0}\), is \(\sigma^{2}=225\).

Step 5 :The alternative hypothesis, \(H_{1}\), is \(\sigma^{2}\neq225\).

Step 6 :\(\boxed{H_{0}: \sigma^{2}=225, H_{1}: \sigma^{2}\neq225}\)
