Best-Selling Albums. The Recording Industry Association of America provides data on the best-selling albums of all time. As of May 28, 2013, the top six best-selling albums of all time (U.S. sales only), are by the artists the Eagles (E), Michael Jackson (M), Pink Floyd (P), Led Zeppelin (L), AC/DC (A), and Billy Joel (B).

(a). List the 15 possible samples (without replacement) of two artists that can be selected from the six. For brevity, use the initial provided.

(b). Describe a procedure for taking a simple random sample of two artists from the six.

(c). If a simple random sampling procedure is used to obtain two artists, what are the chances of selecting P and A? M and E?

Part (a) (E, M), (E, P), (E, L), (E, A), (E, B), (M, P), (M, L), (M, A), (M, B), (P, L), (P, A), (P, B), (L, A), (L, B), (A, B)

Part (b) By Using Random Table, a line number and column number can be chosen first at random, and then two numbers from 1 to 6 are chosen by moving down in the selected column.

Part (c) 0.067.

Step by step solution

01

Part (a) Step 1. Given information.

The given information is:

The Recording Industry Association of America provides data on the best-selling albums of all time. As of May 28, 2013, the top six best-selling albums of all time (U.S. sales only), are by the artists the Eagles (E), Michael Jackson (M), Pink Floyd (P), Led Zeppelin (L), AC/DC (A), and Billy Joel (B).

02

Part (a) Step 2. List the 15 possible samples of two artists that can be selected from the six.

The 15 possible samples (without replacement) of two artists that can be selected from the six best-selling albums of all time:

(E, M), (E, P), (E, L), (E, A), (E, B), (M, P), (M, L), (M, A), (M, B), (P, L), (P, A), (P, B), (L, A), (L, B), (A, B)

03

Part (b) Step 1. Describe a method for choosing two artists from a group of six using simple random sampling.

Procedure:

Using Random Table, two artists out of the given six can be chosen at random.

The artists are listed in order from 1 to 6.

From the Random Table, a line number and column number are chosen at random, and two numbers from 1 to 6 are chosen by moving down in the selected column.

As a result, two artists are chosen at random from a pool of six.

04

Part (c) Step 1. If a simple random sampling procedure is used to obtain two artists, what are the chances of selecting P and A, and  M and E.

Total samples are 15.

There is only one outcome of selecting Pand A.

Therefore, the Chance of selecting Pand A:

=115=0.067

Similarly, there is only one outcome of selecting M and E.

Therefore, the Chance of selecting M and E is:

=115=0.067

Number of Farms.The National Agricultural Statistics Service (NASS) conducts studies of the number of acres devoted to farms in each county of the United States. Suppose that we divide the United States into the four census regions (Northeast, North Central, South, and West), take a simple random sample of counties from each of the four regions, and combine all four simple random samples into one sample. What type of sampling design have we used? Explain your answer.

Surveys that combine one or more of simple random sampling, systematic random sampling, cluster sampling, and stratified sampling employ what is called sampling.

Ghost of Speciation Past. In the article, "Ghost of Speciation Past" (Nature, Vol. 435, pp. 29-31), T. Kocher looked at the origins of a diverse flock of cichlid fishes in the lakes of southeast Africa. Suppose that you wanted to select a sample from the hundreds of species of cichlid fishes that live in the lakes of southeast Africa. If you took a simple random sample from the species of each lake and combined all the simple random samples into one sample, which type of sampling design would you have used? Explain your answer.
