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
well if 6 is half of 12 im sure 60 is half of 120 so A
The upper bound is 56cm I think
