The Atlantic Bluefin tuna is the largest and most endangered of the tuna species. They are found throughout the North Atlantic Ocean and the mean weight is 550 pounds. The Center for Biological Diversity is concerned that this species has been overfished and that the mean weight has decreased. Suppose a random sample of 12 Atlantic Bluefin tuna was obtained from commercial fishing boats and weighed. The summary statistics were x = 535.7 and s = 37.8. Conduct a hypothesis test to determine whether there is any evidence that the mean weight of Atlantic Bluefin tuna has decreased. Assume the distribution of weight is normal and use level of significance a = 0.05. Find bounds for the p value associated with this test. Lower Bound: Upper Bound: 511.68 Incorrect 559.72 Incorrect Suppose that a one-sample t-test for a population mean is being used to test the null hypothesis Ho: = 12.45 against the alternative H: > 12.45, based on data collected from a simple random sample of size 15. The one-sample t-statistic is calculated to be 1.344. Use this table of t-critical values to determine the interval that captures the actual P-value of this test. Different tables have different P-values, so if you use a different table, your answers might not be marked as correct. Enter your answer as a decimal using the precision from the table. If only one limit is in the table, leave the other limit blank. P-value is greater than P-value is less than
