Answer:
The estimated average electric cost amount of all residents in Las Cruces = 182.9
Step-by-step explanation:
The bill amounts from the electric company for the month of July for 10 randomly selected houses from the map was obtained to be
135 265 215 103 156 203 125 156 230 241
Using the Central Limit theory, the mean of a sample extracted randomly from an independent distribution is approximately equal to the population mean of the independent distribution.
This means that the sample mean of a random sample extracted from the population is a good estimate of the population mean.
Sample mean ≈ Population mean
μₓ = μ
Mean = = (Σx)/N
The mean is the sum of variables divided by the number of variables
x = each variable
N = Sample size = 10
Σx = (135+265+215+103+156+203+125+156+230+241) = 1,829
Sample mean = (1,829/10) = 182.9
Population mean ≈ sample mean
Population mean ≈ 182.9

Answer:
2280 minutes.
Step-by-step explanation:
Time spent each week in lessons = (Lessons per week)(Time per lesson)
= (6)(38)
= 228 minutes/week
Time spent in a 10-week period:
10 weeks * 228 minutes/week
= 2280 minutes
Use conversion factors to determine the time in the desired units (i.e. Hours, seconds, etc.).
Hope this helps!
