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

Yuna ran three times as many kilometers so here expression should be 3k and the answer is 36.6

We have given that k = 12. 2

We have to find the expression

<h3>What is the writing and evaluating the expression?</h3>

Expressions are considered to be mathematical statements that have at least of two terms comprised of numbers or variables that should be linked. It could be of addition, subtraction, multiplication, or division.

Write the expression as 3k

Second, substitute 12.2 in for the variable, k.

Third, simplify by multiplying 3 and 12.2.

Therefore the answer is 36.6

Answer:

False (I assume it's a true/false question)

Step-by-step explanation:

Standard deviation measures how spread out the data is. If you add 8 to all the data values, the distribution of data moves to the right (on a graph) 8 units. The shifted data are no more and no less spread out than before. The standard deviation does not change.
