Answer:
c. confidence/probability
Step-by-step explanation:
The margin of error of a confidence interval is:
M = T*s.
In which T is related to the confidence level and s is the standard deviation of the sample.
In which
z is the zscore that has a pvalue of .
Before the sample is chosen
We choose our confidence level, which will determine the value of T. So the first answer is confidence.
After the sample is chosen
We are 95% sure that the true mean is in the sample. So the second answer is probability.
So the correct answer is:
c. confidence/probability
