Suppose that a study was conducted to determine if there is a significant difference in the average temperature of individuals before and after COVID-19 boosters were given. The temperatures of a sample of individuals were obtained before the boosters were given. The following day, their temperatures were again measured. The table below shows the data in degrees Celsius. Temperature before 36.1 35.6 36.0 36.3 37 36.5 Temperature after one day 38.6 37.3 38 37 37.5 38.5
