A look at all Ontario households using natural gas heating in 2012 shows that the mean monthly consumption of natural gas is 107.73 ft³, with the population standard deviation of 13.94 ft³. For a sample of 60 households, the sample mean found was 105.61 ft³. Use this information to find the margin of error E and to construct a 94% confidence interval for the mean monthly consumption for the population of all Ontario households. Is this sample a good estimation of the population mean monthly consumption of natural gas for all Ontario households?
