I need help with question 8. here is what I have said thus far, the instructions say, (8)"Be sure to use the correct parameter when interpreting (in this case the population mean). Also, the data set is measuring nitrate levels of Lost Creek and the units of measure are milligrams per liter (mg/L) so be sure you include that information in the interpretation. A thorough and complete statement about the data set and the interval we are confident the population mean (measured in mg/L) is within."

I have to answer the same question for both data sets. I know the data is correct, I am just worried my response is worded incorrectly. but I am still worried my response is incorrect any help would be appreciated.
