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.

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.

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
