Answer:
Step-by-step explanation:
We are given the following in the question:
Significance level = 0.01
Width of interval = 0.1
Population variance =
We have to find the sample size so that the width of the confidence interval is no larger than 0.1
Formula for sample size:
where E is the margin of error. Since the confidence interval width is 0.1,
Putting these values in the equation:
So, the above expression helps us to calculate the sample size so that the width of the confidence interval is no larger than 0.1 for different sample variances.
Answer:
B. 5.4
Step-by-step explanation:
3/5 = 6/10
6/10 = 0.6

It's easier to see the numbers if you use commas.
6,289,002
The 6 is in the millions place. When rounding, if the following number is 5 or higher, you would round up. If the following number is 4 or less, you would round down. The number following the 6 is a 2, so you would round down. The nearest million would be 6,000,000.
