"In order to estimate the average electric usage per month, a sample of 33 houses were selected and the electric usage determined. The sample mean is 2,000 KWH. Assume a population standard deviation of 106 kilowatt hours. At 99% confidence, compute the upper bound of the interval estimate for the population mean."

2,157.89 KWH is the upper bound of the interval estimate for the population mean.

Step-by-step explanation:

We are given the following in the question:

Sample mean, = 2,000 KWH

Sample size, n = 33

Alpha, α = 0.01

Population standard deviation, σ = 106 KWH

99% Confidence interval:

Putting the values, we get,

2,157.89 KWH is the upper bound of the interval estimate for the population mean
