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 ) 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? = ) 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.
