Criteria for checking: Step 1- 2 points Step 4-5 points Step2-1point Step5- 2 points Step3-2 points Step6-2 points 1. Ten randomly selected gold mines produced an average of 21 barrels of gold per day with standard deviation of 1.56. Is it enough evidence to conclude that the gold mines are not producing an average of 22.5 barrels of gold per day? Use 1% level of significance. 2.
