The data below represent the nationwide highest yields for one-year CDs and five-year CDs.

One-Year CD	Five-Year CD
5.34	5.94
5.30	5.89
5.30	5.82
5.29	5.82
5.24	5.79

a.	For one-year CDs and five-year CDs, separately compute the variance, standard deviation, range, and coefficient of variation.

(Round to four decimal places as needed.)

Part 5

Now consider the data for five-year CDs.

The variance is

enter your response here.

(Round to five decimal places as needed.)

Part 6

The standard deviation is

enter your response here.

(Round to four decimal places as needed.)

Part 7

The range is

enter your response here.

(Type an integer or a decimal. Do not round.)

Part 8

The coefficient of variation is enter your response here%.

(Round to four decimal places as needed.)

Part 9

b. Choose the correct answer below.

A.

One-year CDs have more variation because they have a lower variance, standard deviation, range, and coefficient of variation.

B.

The two investments have approximately the same variation since the difference in their standard deviations is less than 0.1.

C.

Five-year CDs have more variation because they have a higher variance, standard deviation, range, and coefficient of variation.

D.

It cannot be determined.
