(Include the numbers for yourdecision)) Write a conclusion in context. (This is the answer tothe hypothesis test. Make sure it includes context.)g) Which type of error can the statistician have made inthe correct conclusion of this hypothesis test? (This isnot an error that can be avoided.)h) Can we state the probability with which this error willoccur? If so, state the value. In the following two hypothesis test problems, the teststatistic (z-score) will be given. Following these is aseparate problem for which you will have to calculatethe z-score using the appropriate formula.1. Swimming at local beaches is affected by the number ofbacteria in the water. Bacteria numbers are monitored bytaking water samples. In the summer, the mean numberof E.Coli bacteria in a water sample at local beaches hasusually been 97. The standard deviation is known to be15. If this August 62 water samples from beachesaround Annapolis were analyzed and the mean numberof E. Coli bacteria found to be 102, does this mean thatsummertime E. Coli bacteria levels have increased? Usea significance level of 1% for this test. (Note: In part (d),the test statistic (z-score) is GIVEN.)a)10297o =15n =62a =0.01b) Why is a hypothesis test based on the normaldistribution justified? (Explain.
