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 1007, 2226, 2232, 2209. Required:
a. Find the standard error.
b. To testÂ H0:Î¼=1000Â vs,Â Ha:Î¼>100 0, find the test statistic. Use the answer from part a for the standard error.
c. Find p-value.
d. Explain how your one-sided analysis implicitly tests the broader null hypothesis thatÂ Î¼â¥1000.
