Government resulations restrict the amount of pollutants that can be released to the atmosphere through industrial smokestacks. To demonstrate that their smokestacks are releasing poliutants below the mandated limit of 7 parts per bilion pollutants. REM industries coliects a random sample of 26 readings. The mesn poliutant level for The sample is 6.75 parts per billion weh a population sandard deviation or 0.7 parts per billion. Do the dara support the ciam thar the average pollitants produced by HeM 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.
