Test the claim that the two samples described below come from populations with the same mean. Assume that the samples are independent simple random samples. Use a significance level of 0.04. Sample 1: n=100, ave 1=12, SD 1=4.5. Sample 2: n=93, ave 2=17, SD 2 =5. Test Statistic?= P-Value?= Solution Test statistic would be (17-12)/sqrt (4.5^2/100+ 5^2/93) 5/0.6865=7.28 P value is <.0005 so they probably didn\'t..
