Question

What is meant by the 95% confidence interval of the mean?

a.That 5% of my sample is not OK.

b.That 95% of my sample is OK to do more tests.

c.That I am 95% confident that the confidence interval will contain the parameter being estimated.

d.That I am 95% sure that the population mean is 95.

Answer 1

Option c.

Explanation:

Confidence interval refers to an interval such that there is a probability that the value of a parameter lies within that interval.

Therefore,
`95\%` the confidence interval of the mean means that there is a probability that the value of a parameter lies within that confidence interval.

So, option c. is correct
