Why? c} Perform a hypothesis testing under alpha=.5. Whether the true average concentration in the bottom water is different from that of surface water? What is the test statistic? What is the degree of freedom? What is the p-value? What is your conclusion? d} Construct a 95% condence interval for the different between the two groups. e} Could you infer the same conclusion from the 95% confidence interval as you made in [c]? How
