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 a population standard deviation of 13.9a ft3. For a sample of 6a households, the sample mean found was 105.6a ft3. Use this information to find value, the margin of error E, and to construct a 93% 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? (a=1)
