Answer:
The company should take a sample of 148 boxes.
Step-by-step explanation:
Hello!
The cable TV company whats to know what sample size to take to estimate the proportion/percentage of cable boxes in use during an evening hour.
They estimated a "pilot" proportion of p'=0.20
And using a 90% confidence level the CI should have a margin of error of 2% (0.02).
The CI for the population proportion is made using an approximation of the standard normal distribution, and its structure is "point estimation" ± "margin of error"
[p' ± ]
Where
p' is the sample proportion/point estimator of the population proportion
is the margin of error (d) of the confidence interval.
So
n= 147.28 ≅ 148 boxes.
I hope it helps!
Answer:
2,850
Step-by-step explanation:
4.25 x 9 = 38.25
4.25 x 13 = 55.25
4.25 x 12 = 51
13.70 x 92 = 1260.4
3.28 x 130 = 426.4
8.06 x 126 = 1015.56
all totals would equal 2,846.86, which to the nearest would be $2,850
-6x-x^2-8 = -(x+2) x (x+4)
(This is if you are factoring the expression)
