The daily electrical energy consumption (in Watts) during July for a random sample of 16 households was recorded. The mean was 3307 W and the standard deviation was 327 W. Assume the underlying distribution of the consumption is normal. Find the lower confidence limit (LCL) of the 95% confidence interval for the mean daily electrical energy consumption during that month. Round your answer to the nearest whole number (integer).
