Are these results very different from the confidence interval 26.6 hg < u < 31.2 hg with only 14 sample values, x = 28.9 hg, and s = 3.3 hg? What is the confidence interval for the population mean u? hgWe have developed a new drug used to reduce fever and want to test its efficacy. Ten ER patients who are running a fever agree to take the new drug instead of the traditional treatment. Their temperatures are taken before the drug is administered and 30 minutes after taking the drug. The results are recorded in the Excel file below. Use the data to construct and interpret a 99% confidence interval for the mean change in temperatures of patients after taking this drug using Excel. Be sure to include any explanation necessary along with a sentence that explains what the interval means.
