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.Sample 1: n1=24, x?? 1=14, s1=4.Sample 2: n2=28, x?? 2=9, s2=4.(a) The test statistic is ___.(b) Find the t critical value for a significance level of 0.02 for an alternative hypothesis that the first population has a larger mean (one-sided test): t?= ___.(c) The conclusion is-There is not sufficient evidence to warrant rejection of the claim that the two populations have the same mean.-There is sufficient evidence to warrant rejection of the claim that the two populations have the same mean and accept that the first population has a larger mean.
