Question:

Standards set by government agencies indicates that American should not exceed an average daily sodium intake of 3300 milligrams (mg). To find out whether Americans are exceeding this limit, a sample of 100 American is selected, and the mean and standard deviation of daily sodium intake are found to be 3400 mg and 1100 mg, respectively. Use ? = 0.05 to conduct a test of hypothesis (Use both Critical Value approach and p-value approach).
