### State the decision rule, using the 0.05 significance level.(Round y.pdf

• 1. State the decision rule, using the 0.05 significance level.(Round your answer to 3 decimal places.) The null hypothesis and the alternate are: Solution similar The null hypothesis and the alternate are: H0: The frequencies are equal. H1: The frequencies are not equal. Category f0 A 30 B 30 C 25 D 15 (a) State the decision rule, using the 0.01 significance level. (Round your answer to 3 decimal places.) Reject H0 if 2 > (b) Compute the value of chi-square. (Round your answer to 1 decimal places.) x2 (a) For 0.01 significance and df = 3, critical Chi-square = 11.345 If the calculated chi-square is greater than or equal to 11.345, reject the null hypothesis. (b) E = 25
• 2. calculated chi-square = sum[(Oi - E)^2 /E] = 6 Since calculated chi-square is less than 11.345, it can be said that the frequencies are equal.
