A confidence interval of .99 can correctly be interpreted to mean that:

a. 99% of the time in repeated sampling intervals using an appropriate formula will contain the sample value.

b. 99% of the time in repeated sampling intervals using an appropriate formula will contain the relevant population parameter

c. 99% of the time in repeated sampling intervals using an appropriate formula will contain the sample value as the midpoint of the interval

d. 99% of the time in repeated sampling intervals using an appropriate formula will contain the sample mean as their midpoints.

Answer #1

Confidence interval we find for population parameters. Hence, Option b) 99% of the time in repeated sampling intervals using an appropriate formula will contain the relevant population parameter is the correct answer.

Rest are talking about sample mean so not useful.

I hope this will help. Thank you.

    3. Question 3 Aa Aa E A confidence interval estimate is an estimate of a population parameter providing an interval that is believed (with a certain level of confidence) to contain the value of the population parameter. The confidence level is the level of confidence associated with the confidence interval estimate. If your confidence level is 94%, then if you were to employ repeated sampling and compute the confidence interval estimate for each sample, you would expect % of the...
