4,034.06 ,5,965.94 are confidence interval for the population average wages at the factory.
What is confidence interval estimation?
Your estimate's mean plus and minus the range of that estimate's fluctuation is called a confidence interval.
If you repeat your test, you can expect your estimate to fall between these numbers with a reasonable degree of certainty. Another term for probability in statistics is confidence.
The formula for confidence interval estimation is:
μ = M ± Z(sM)
where:
M = sample mean
Z = Z statistic determined by confidence level
sM = standard error = √(s2/n)
M = 50000
Z = 2.58
sM = √(30002/64) = 375
μ = M ± Z(sM)
μ = 50000 ± 2.58*375
μ = 50000 ± 965.94
μ = 4,034.06 ,5,965.94

Answer:
1.5
Step-by-step explanation:
y=2x - 3
0 = 2x - 3
-2x = - 3 /÷(-2)
x = 3 ÷ 2
x = 1.5 3/2
Answer:
These are called supplementary angles.
Step-by-step explanation:
Supplementary angles are equal to 180 degrees. 100 + 80 is equal to 180 degrees, meaning that the angles are supplementary. I hope this helps! :)
The first one
Running forward is adding
Running opposite direction is subtracting
5-5
5-6
6-5
6-0
5-5 is the only one that equals 0
Using a calculator would show that
![9/11 = 0.818181\ldots = 0.\overline{81}](https://tex.z-dn.net/?f=9%2F11%20%3D%200.818181%5Cldots%20%3D%200.%5Coverline%7B81%7D)
The horizontal line over top means the "81" repeats forever.
You can use long division as an alternative method to getting the answer above.
