An industrial plant claims to discharge no more than 1000 gallons of wastewater per hour, on the average, into a neighboring lake. An environmental action group decides to monitor the plant, in case this limit is being exceeded. A random sample of four hours is selected over a period of a week. The observations are 1625, 2045, 2332, 2096. a. Find the standard error. se = 147.11 (Round to two decimal places as needed.) b. To test Ho: μ = 1000 vs. Hu>1000, find the test statistic. Use the answer from part (a) for the standard error. t= (Round to two decimal places as needed.)

Transcribed Image Text:An industrial plant claims to discharge no more than 1000 gallons of wastewater per hour, on the average,
into a neighboring lake. An environmental action group decides to monitor the plant, in case this limit is being
exceeded. A random sample of four hours is selected over a period of a week. The observations are 1625,
2045, 2332, 2096.
a. Find the standard error.
se = 147.11 (Round to two decimal places as needed.)
b. To test Ho: μ = 1000 vs. H₂: > 1000, find the test statistic. Use the answer from part (a) for the standard
error.
