Independent samples: Use the sample data to test the claim the two populations have the same mean. Do not pool the data. Assume all requirements are met. Sample 1 Sample 2 x¯=45 s=3 n=123 x¯=44 s=4 n=341 Is this a left, right, or two tailed test? What is the P-value? Will the null hypothesis be rejected? Use a 1% level of significance.
