The Environmental Protection Agency(EPA) recommends that concentrations of the carcinogen icinsecticide mirex found in salmon, be at a level of no morethan0.08 parts per million. Researchers tested 75 randomly chosen farm raised salmon from 45 different farms and found the mean concentration of mirex to be 0.0853 with a standard deviation of 0.0315. A histogram of the distribution was fairly symmetric and showed no outliers. Are farm raised salmon contaminated beyond the level permitted by the EPA? Use a significance level of 0.01. a) State the hypotheses in symbols. b) Use your calculator to perform a 1-Sample t-Test and report the test statistic and p-value. use the T-Test command in your graphing calculator found under STAT-Tests. Write out what you entered in your calculator. c)Write a full conclusion for this test in the context of the problem d)Find a 98% confidence interval for the mean amount of mirex found in farm-raisedsalmon. Use the T-Interval command in your graphing calculator found under STAT–TESTS. Write out what you entered in your calculator.

The Environmental Protection Agency(EPA) recommends that concentrations of the carcinogen icinsecticide mirex found in salmon, be at a level of no morethan0.08 parts per million. Researchers tested 75 randomly chosen farm raised salmon from 45 different farms and found the mean concentration of mirex to be 0.0853 with a standard deviation of 0.0315. A histogram of the distribution was fairly symmetric and showed no outliers. Are farm raised salmon contaminated beyond the level permitted by the EPA? Use a significance level of 0.01.
a) State the hypotheses in symbols.
b) Use your calculator to perform a 1-Sample t-Test and report the test statistic and p-value. use the T-Test command in your graphing
calculator found under STAT-Tests. Write out what you entered in your calculator.
c)Write a full conclusion for this test in the context of the problem
d)Find a 98% confidence interval for the mean amount of mirex found in farm-raisedsalmon. Use the T-Interval command in your graphing
calculator found under STAT–TESTS. Write out what you entered in your calculator.
