1 48 & myopenmath.com @ 1hr58mins x The FDA regulates that fish that is consumea 15 auowea to contain 1.0 mg/kg of mercury. In Arkansas, bass fish were collected in 54 different lakes to measure the amount of mercury in the fish. The data for the average amount of mercury in each lake is in the table. Do the data provide enough evidence to show that the fish in Arkansas lakes has more mercury than the allowable amount? Test at the 10% level. Average Mercury Levels (mg/kg) in Fish 1.62 | 0.6]0.92 1.5 1.32 [ 0.74 | 1.09 | 1.19 | 0.77 [ 0.89 | 1.49 | 1.2 | 1.47 | 1.02 1.15 0.92 1.37 12 0.82 152 1.45 1.33 1.25 07 1.12 | 0.64 1.1 | 1.35 1 State the hypotheses. Hp:p 22 ' | Hpp 2 ' | Calculate the test statistic. Round to three decimal places. %= | Calculate the standardized test statistic. Round to three decimal places. | Find the p-value. Round to four decimal places. p-value = ' | State your decision. () Since the p-value is greater than 0.1, reject Hg. () Since the p-value is less than 0.1, fail to reject Hp. () since the p-value is greater than 0.1, fail to reject Hg. (O since the p-value is less than 0.1, reject H,. Interpret the results. () At the 10% level of significance, there is enough evidence to conclude that the mean amount of mercury in bass fish in Arkansas is less than the allowable amount of 1.0 mg/kg. () At the 10% level of significance, there is enough evidence to conclude that the mean amount of mercury in bass fish in Arkansas is not equal to the allowable amount of 1.0 mg/kg. () At the 10% level of significance, there is not enough evidence to conclude that the mean amount of mercury in bass fish in Arkansas is more than the allowable amount of 1.0 mg/kg. () At the 10% level of significance, there is not enough evidence to conclude that the mean amount of mercury in bass fish in Arkansas is not equal to the allowable amount of 1.0 mg/kg. ) At the 10% level of significance, there is not enough evidence to conclude that the mean amount of mercury in bass fish in Arkansas is less than the allowable amount of 1.0 mg/kg. ) At the 10% level of significance, there is enough evidence to conclude that the mean amount of mercury in bass fish in Arkansas is more than the allowable amount of 1.0 mg/kg
