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