An article reported that for a sample of 20 kitchens with gas cooking appliances monitored during a one-week period, the sample mean CO2 level (ppm) was 654.16, and the sample standard deviation was 164.43. Assume that the CO2 level (ppm) is normally distributed. Which of the following is used in order to calculate a 95% confidence interval for true average CO2 level in the population of all homes from which the sample was selected? Lütfen birini seçin: O a. 7...
