Answer:
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
Answer:
Rate of snow fall per hour ≥ 1 inches per hour
Step-by-step explanation:
Given:
Amount of snow already settled = 4 inches
Time period of snow fall = 2 hour
New amount of snow = least 6 inches
Computation:
Extra amount of snow ≥ New amount of snow - Amount of snow already settled
Extra amount of snow ≥ 6 - 4
Extra amount of snow ≥ 2 inches
Rate of snow fall per hour ≥ Extra amount of snow / Time period of snow fall
Rate of snow fall per hour ≥ 2 / 2
Rate of snow fall per hour ≥ 1 inches per hour
Answer:
B. Graph of a one-to-one function.
Step-by-step explanation:
A one-to-one function will have a unique value, y, for each different value of x. The graph displayed will have values very, very close to each other as x approaches ±4, but they won't be the same even at higher values of x.
