Test the claim about the difference between two population means ₁ and ₂ at the level of significance a. Assume the samples are random and independent, and the populations are normally distributed. Claim: ₁₂0.01 Population statistics: o, 3.5, 0₂ = 1.5 Sample statistics: x, 16, n₁ =30, x₂ =18, n₂ = 26 # GUS Determine the alternative hypothesis. Determine the standardized test statistic z=(Round to two decimal places as needed.) Determine the P-value FO P-value (Round to three decimal places as needed.) RET What is the proper decision? P OA. Reject Ho. There is not enough evidence at the 1% level of significance to reject the claim.. OB. Fail to reject Ho. There is not enough evidence at the 1% level of significance to reject the claim OC. Reject Ho. There is enough evidence at the 1% level of significance to reject the claim. 50
