The daily electrical energy consumption (in Watts) during July for a random sample of 18 households was recorded. The mean was 3399 W and the standard deviation was 316 W. Assume the underlying distribution of the consumption is normal. Find the marging of error E of the 95% confidence interval for the mean daily electrical energy consumption during that month. Round your answer to two decimal places.
