4. The Canadian Costal Health Society warned that the East Creek was contaminated. They took a random sample of locations in the East Creek and recorded the coliform count (bacteria per 100 ml of water) in early August and then again in October at the same locations after several rainstorms. Report the appropriate summary statistics for each sample. Test the claim that the true mean coliform is different before and after the rainstorms using both a hypothesis test and a confidence interval and a = 0.05. Be sure to state which type of test you are using, the null and alternative hypotheses, the test statistic, p-value, decision and conclusion. Be sure to interpret the Cl in the terms of the problem.

3. To compare the effect of the declining bee population on honey production, independent samples of Hives in Kentucky and Missouri were selected and the amount of honey harvested (in pounds) from each were recorded. Assume that the underlying populations are normal. Report the appropriate summary statistics for each sample. Test the claim that the true mean honey harvest per hive is different in the two states using both a hypothesis test and a confidence interval and a = 0.05. Be sure to state which type of test you are using, the null and alternative hypotheses, the test statistic, p-value, decision and conclusion. Be sure to interpret the Cl in the terms of the problem. 4. The Canadian Costal Health Society warned that the East Creek was contaminated.
