Mercury levels were collected on 43 random specimens of Albacore tuna, the average mercury levels was found to be 0.358 parts per million (ppm) and the standard deviation of mercury level was 0.138 (ppm). The FDA website reports that the average mercury level in all Albacore tuna is 0.391 ppm. The researchers wish to know if the average mercury level in Albacore tuna is different from what is reported on the FDA website. Test the hypothesis at 5% level of significance. Calculate the p-value to perform the test at 5% level of significance. (Hint: p-value is dependent on the direction of the alternative and the test statistic value)
