Test the claim about the difference between two population means , and l2 at the level of significance a. Assume the samples are random and independent, and the populations are normally distributed. Claim: 4, SH2; a =0.05. Assume o, *o Sample statistics: X1 =2417, s, = 177, n, = 12 and x2 = 2296, s2 = 55, n2 = 11 Find the standardized test statistic t. (Round to two decimal places as needed.) Find the P-value. (Round to three decimal places as needed.) Decide whether to reject or fail to reject the null hypothesis and interpret the decision in the context of the original claim. VHo: There V enough evidence at the 5% level of significance to reject the claim.
