Question 3 To determine the temperature of the air in an exhaust duct at full plant operation, forty (40) measurements are taken over a short period of time. The average of the measurements was found to be 1104 °C, and the standard deviation of the sample was 12°C. Determine the 90% confidence interval for the temperature of the air in the exhaust duct during full plant operation.
