Provided below are summary statistics for independent simple random samples from two normal populations. Conduct the required hypothesis test x1=21, s1=3, n1=21, x2=25, s2=4, n2=17 Left-tailed test, α=0.05 What are the correct hypotheses for a left-tailed test? A. H0: μ1=μ2 Ha: μ1≠μ2 B. H0: μ1>μ2 Ha: μ1=μ2 C. H0: μ1=μ2 Ha: μ1>μ2 D. H0: μ1<μ2 Ha: μ1=μ2 E. H0: μ1≠μ2 Ha: μ1=μ2 F. H0: μ1=μ2 Ha: μ1<μ2 Compute the test statistic. t=? (Round to three decimal places as needed.) Determine the P-value. p-value=? (Round to four decimal places as needed.) Since the P-value is (equal to or less) (greater) than α, (reject) (do not reject) H0.
