Oklahoma State Officials. The five top Oklahoma state officials are displayed in Table 1.2 on page 11. Use that table to solve the following problems.

(a) List the possible samples of size 1 that can be obtained from the population of five officials.

(b) What is the difference between obtaining a simple random sample of size 1 and selecting one official at random?

(c) List the possible samples (without replacement) of size 5 that can be obtained from the population of five officials.

(d) What is the difference between obtaining a simple random sample of size 5 and taking a census of the five officials?

Short Answer

Expert verified

Part (a) G, L, S, A, T.

Part (b) There is no difference between collecting a basic random sample of size 1 and selecting one official at random.

Part (c)Sample:- G, L, S, A, T.

Part (d) There is no difference between taking a census of the five officials and obtaining a simple random sample of size 5.

Step by step solution

01

Part (a) Step 1. Given information.

The given information is:

The five top Oklahoma state officials are displayed in Table 1.2 on page 11. Use that table to solve the following problems.

02

Part (a) Step 2. List the possible samples of size 1 that can be obtained from the population of five officials.

Make a list of the possible samples of size 1 from a population of five officials.

Governor (G)

lieutenant General (L)

Secretary of State (S),

Attorney General (A)

Treasurer (T)

They are the five officers listed in Table 1.2.

As a result, the following are the possible samples of size 1 from the given population:

Samples: G, L, S, A, T

03

Part (b) Step 1. Difference between obtaining a simple random sample of size 1 and selecting one official at random 

It is evident from part (a) that the specified population has 5 samples of size 1.

Furthermore, each sample has an equal probability of being chosen.

As a result, there is no difference between collecting a basic random sample of size 1 and selecting one official at random.

04

Part (c) Step 1. List the possible samples (without replacement) of size 5 that can be obtained from the population of five officials. 

From a population of five officials, make a list of the potential size 5 samples without replacement.

Because there are five officials, there is only one sample in which the size 5 sample is available,

Sample:- G, L, S, A, T

05

Part (d) Step 1. Difference between obtaining a simple random sample of size 5 and taking a census of the five officials.

Part (C) shows that for the given population, there is only one sample of size 5 (without replacement).

Furthermore, each sample has an equal probability of being chosen.

As a result, there is no difference between taking a census of the five officials and obtaining a simple random sample of size 5.

Ideally, in cluster sampling, each cluster should the entire population.

In a designed experiment, there are two factors, say, Factor Aand Factor B. Factor Ahas three levels, say, a1,a2anda3; Factor Bhas four levels, say,b1,b2,b3andb4.

(a) Construct a schematic for the treatments similar to Table 1.8 on page 27.

(b) Use part ( a ) to determine the number of treatments.

(c) Could you have determined the answer for part ( b ) without constructing the schematic in part ( a )? Explain your answer.

Genocide. The document "American Attitudes about Genocide" provided highlights of a nationwide poll with 1000 participants. The survey, conducted by Penn Schoen Berland between June 30 and July 10, 2012, revealed that "66% of respondents believe that genocide is preventable."

(a). Is the statement in quotes an inferential or a descriptive statement? Explain your answer.

(b). Based on the same information, what if the statement had been "66% of Americans believe that genocide is preventable"?

Explain why a census is often not the best way to obtain information about a population.

In Exercises 1.17-1.22, state whether the investigation in question is an observational study or a designed experiment. Justify your answer each case.

The Salk Vaccine. In the 1940s and early 1950s, the public greatly concerned about polio. In an attempt to prevent this disease, Jonas Salk of the University of Pittsburgh developed a polio vaccine. In a test of the vaccine's efficacy, involving nearly million grade-school children, half of the children received the Salk vaccine; the other half received a placebo, in this case, an injection of salt dissolved in water. Neither the children nor the doctors performing the diagnoses knew which children belonged to which group, but an evaluation center did. The center found that the incidence of polio was far less among the children inoculated with the Salk vaccine. From that information, the researchers concluded that the vaccine would be effective in preventing polio for all U.S. school children; consequently, it was made available for general use.
