Answer:

This cannot be simplified, so all I can give is that this is between 21 and 22, and that it is about 21.954. If you need the decimals you should put this into a calc (apparently inappropriate)

Step-by-step explanation:

Here's the explanation for why this is between 21 and 22

22^2 is 484 and 21^2 is 441. Since the number inside of the square root is 482, and this is between 484 and 441, you know that the number \sqrt{482} is equal to is between 21 and 22, and closer to 22 than it is to 21.

The 95% confidence interval for a population mean (context unknown and irrelevant) turns out to be (428, 510). What is E?
Elina [12.6K]

The 95% confidence interval for a population mean has a margin of error (E) of 41

The confidence interval for a population mean is given by:

Confidence interval = μ ± E = (μ - E, μ + E)

Where μ is the mean and E is the margin of error.

Since the confidence interval is (428, 510), hence:

μ - E = 428      (1)

μ + E =  510     (2)

Subtracting equation 1 from equation 2:

2E = 82

E = 41

μ - E = 428

μ -41 = 428

μ = 469

Hence the margin of error (E) is 41
