Answer:
A. there is a 99% probability that μ is between 3 and 9.
Step-by-step explanation:
From a random sample, we build a confidence interval, with a confidence level of x%.
The interpretation is that we are x% sure that the interval contains the true mean of the population.
In this problem:
99% confidence interval.
6 ± 3.
So between 6-3 = 3 and 6 + 3 = 9.
So we are 99% sure that the true population mean is between 3 and 9.
So the correct answer is:
A. there is a 99% probability that μ is between 3 and 9.

Travel distance by light in a second = 3*10^5 kms
Travel distance by light in 60 seconds =
3*10^5 * 60
180 * 10^5
1.8 * 10^7 kms
<span>If you have a high confidence level, the chance of rejecting the null hypothesis is rare.
If you have a low confidence level, the chance of of rejecting the null hypothesis is nonexistent.
If you have a low confidence level, the chance of of rejecting the null hypothesis is rare.
If you have a high confidence level, the chance of of rejecting the null hypothesis is high.</span>
