Question 309547: . After a sample of numbers is taken from a population, the 95% confidence interval is calculated out at {10.5, 12.0}
What is the correct way to interpret this confidence interval? Choose one.
A) 95% of all values in the population are between 10.5 and 12.0
B) The true population mean has to be between 10.5 and 12.0
C) There is a 95% probability that the true population parameter is between 10.5 and 12.0.
D) The mean is between 10.5 and 12.0, and the standard deviation is 95.

You can put this solution on YOUR website! After a sample of numbers is taken from a population, the 95% confidence interval is calculated out at {10.5, 12.0}
What is the correct way to interpret this confidence interval? Choose one.
------
None of those choices is correct.
The correct answer is "We are 95% confident that the population mean
is between 10.5 and 12."
-------------------
The confidence interval is not a probability statement and it is not
an ascertion that the pop mean is between thus and thus.
