MY NOTES P 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 monito this limit is being exceeded. A random sample of 42 hours is selected over a period of a month. The data are unimodal and roughly symmetric. X=1125, s=652, and Standard Error=100.606 (a) Using StatCrunch, the p-value=[0.034 (b) Are the conditions met to conduct this test? x (3 decimal places) Yes, the population is approximately normal because n > 30. No, np and n(1-p) are not both > 15. Yes, np and n(1-p) are both > 15. Yes, because the data are approximately normal. х (c) At alpha=0.05, which of the following is the correct conclusion? Do not reject the null hypothesis. There is evidence that the wastewater discharged by the industrial plant exceeds 1000 gallons per hour. Reject the null hypothesis. There is sufficient evidence that the wastewater discharged by the industrial plant exceeds 1000 gallons per hour. Reject the null hypothesis. There is insufficient evidence that the wastewater discharged by the Industrial plant exceeds 1000 gallons per hour. Do not reject the null hypothesis. There is insufficient evidence that the wastewater discharged by the industrial plant exceeds 1000 gallons per hour. X
