c)
When you create a 99% confidence interval this indicates that If you made many intervals by taking samples of the same size from a population then...99% of all of the intervals that you make will contain the true population mean.
It would not contain 99% of the population.
You cannot say anything about the probability of one interval that you created.
I do know that 99 is larger than 95 so you will have a wider interval.
Can anyone help me with this?
Which of the following statements is true about a 99% confidence interval?
a. The interval contains 99% of the population.
b. The probability that the population mean is in the interval is 99%.
c. The interval is wider than a 95% confidence interval would be.
d. None of the above.
