Answer:
a range of values such that the probability is C % that a rndomly selected data value is in that range
Step-by-step explanation:
complete question is:
Select the proper interpretation of a confidence interval for a mean at a confidence level of C % .
a range of values produced by a method such that C % of confidence intervals produced the same way contain the sample mean
a range of values such that the probability is C % that a randomly selected data value is in that range
a range of values that contains C % of the sample data in a very large number of samples of the same size
a range of values constructed using a procedure that will develop a range that contains the population mean C % of the time
a range of values such that the probability is C % that the population mean is in that range

Answer:
A. 
Step-by-step explanation:
For this problem, we have to combine like terms.
Let's look at the equation:

,
,
do not have any other like terms, so we keep all in the final answer.
and
are like terms, so we combine them. 
14 and 6 are like terms, so we combine them. 14+6 = 20
Let's put everything into the final equation:

So, the final answer is A.
