Answer:
Step-by-step explanation:
What is the margin of error if the sample size is 100, sample mean is 68.0, and standard deviation is 4.0
The Margin of error formula =
± z score × s/√n
Where s = standard deviation= 4
n= Number for samples = 100
z = z score of confidence interval
Margin of error = ± z × 4/√100
Margin of error = ±z × 4/10
=± z × 2/5
= ± z × 0.4
= ± 0.4z
Margin of error = ± 0.4z
Where is the rest of the question?
This can be the equation, if you put it in x and you put it in y. So x plus y is equal to 30,000, 5/100x plus 11 over 100y is equal to 2200. The answer is y is equal to 70, 000 over 6. X = 11000/6
4 3/6- 3 5/6= 3 9/6- 3 5/6= 4/6=2/3
