Test the claim about the difference between two population means , 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 parameters: a, 3.2, 0₂ = 1.6 Sample statistics: x, 17. n₁ =29. x₂=19, n₂ = 28 H₂H₁ H₂ Determine the standardized test statistic 2=-2.99 (Round to two decimal places as needed.) Determine the P-value. P-value = 0.003 (Round to three decimal places as needed.) 1 M" IWI HEIDE S ₂ (4)

Assume the samples are random and independent, and the populations are normally distributed Claim: ₂0.01 Population parameters: o, 3.2, 0₂1.6 Sample statistics: x, 17, n, 29, x₂-19, n₂ =28 What is the proper decision? OA. Reject Ho. There is not enough evidence at the 1% level of significance to reject the claim. B. Reject Ho. There is enough evidence at the 1% level of significance to reject the claim OC. Fail to reject Ho. There is not enough evidence at the 1% level of significance to reject the claim. OD. Fall to reject Ho. There is enough evidence at the 1% level of significance to reject the claim s' GLED IMI S (KA) More
