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 8 parts per billion pollutants, REM Industries collects a random sample of 27 readings. The mean pollutant level for the sample is 7.75 parts per billion with a population standard deviation of 0.9 parts per billion. Do the data support the claim that the average pollutants produced by REM Industries are below the mandated level at a 0.02 significance level? Assume the population of readings is approximately normally distributed. Step 2 of 3 : Compute the value of the test statistic. Round your answer to two decimal places.

Question

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 8 parts per billion pollutants, REM Industries collects a random sample of 27 readings. The mean pollutant level for the sample is 7.75 parts per billion with a population standard deviation of 0.9 parts per billion. Do the data support the claim that the average pollutants produced by REM Industries are below the mandated level at a 0.02 significance level? Assume the population of readings is approximately normally distributed.

Step 2 of 3 :

Compute the value of the test statistic. Round your answer to two decimal places.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
