Government regulations restrict the amount of pollutants that can be released to the atmosphere through industrial smokestacks. To demonstrate that their smokestacks are releasing pollutants below the mandated limit of 5 parts per billion pollutants, REM Industries collects a random sample of 23 readings. The mean pollutant level for the sample is 4.45 parts per billion with a population standard deviation of 1.3 parts per billion. Do the data support the claim that the average pollutants produced by REM Industries are below the mandated level at a 0.01 significance level? Assume the population of readings is approximately normally distributed. Step 3 of 3: Draw a conclusion and interpret the decision.
