FDA is testing a new drug for its effectiveness in improving lung functions of Covid patients. Thedrug is considered "effective" and hence approved if it increases the blood oxygen level by an averageof 5 points. FDA selected a random sample of 7 individuals and recorded their blood oxygen level beforeand after taking the drug. The results are in the following table.PersonMike Mina Sophia Ibrahim Silvia Carl GeorgeOxygen level before drug86859485918892Oxygen level after drug95929795989897Construct and interpret 95% confidence interval for the difference in oxygen levels before and after thedrug use.
