article reported that for a sample of 54 kitchens with gas cooking appliances monitored during a one-week period, the sample mean Co, level (ppm) was 654.16, and the sample standard d 1.38. (a) Calculate and interpret a 95% (two-sided) confidence interval for true average Co, level in the population of all homes from which the sample was selected. (Round your answers to places.) X, 699.03 ]× ) 609.29 ppm Interpret the resulting interval. O we are 95% confident that this interval contains the true population mean. O we are 95% confident that the true population mean lies below this interval. O we are 95% confident that this interval does not contain the true population mean. O we are 95% confident that the true population mean lies above this interval.
