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:
it's d
Step-by-step explanation:
≤ may refer to:
Inequality (mathematics), relation between values; a ≤ b means "a is less than or equal to b"
so the answer D is right because the face always ponit to the bigger number if x is -14 then this stament would be true
STEP 1:
Find the $ total sold. Multiply total pounds by $2 sale price per pound.
=4,913,977 pounds * $2 a pound
=$9,827,954 total sold
STEP 2:
Divide the total sold above by the 325 shrimpers.
=$9,827,954 ÷ 325
=$30,239.858
Rounded to nearest dollar:
Each of the 325 shrimpers will take home $30,240.
Hope this helps! :)
Answer:
The slope of this line is <u>1/5</u>
Step-by-step explanation:
You can find the answer easily by graphing the problem. In doing so, you will find the slope (rise over run) to be one over five. This is because you rise one unit, and run five.
