The objective of this assignment is for you to personally create a fully documented artificial (i.e. you make it up) example of a hypothesis test of a claim about a population proportion parameter using the Critical Value Method just like you might see in a textbook. Please do not copy an example from the Internet or a textbook. Also, while I expect you to learn from other students' submissions, if in my opinion your post too closely resembles another student's I will ask you to revise it.

Please use the following outline for your response:

I) Description of problem and statement of claim and test.

The proportion of kindergarten students in the DEF School District who walk to school is equal to 10%

The proportion of drivers who live in the city of GHI who listen to the radio while driving is less than 40%

B) State the claim symbolically (i.e. using mathematical symbols). For the above example claims this would look like:

p > 0.75

p = 0.10

p < 0.40

II) Statement of null hypothesis.

State H0. (Hint: Given your symbolic claim above, follow the flowchart in Figure 8-2 (p. 385) to identify H0. It will be a mathematical expression with p and an equal sign.)

III) Statement of alternative hypothesis.

State H1. (Hint: Given your symbolic claim above, follow the flowchart in Figure 8-2 (p. 385) to identify H1. It will be a mathematical expression with p and either a greater-than sign, a less-than sign, or a not-equal sign.)

IV) Description of sampling plan

(Hint: You should describe a procedure for obtaining a random sample from the stated population and since you are testing a population proportion, the end result should be some number of "successes", say x, out of a sample size of n where you create x and n for the purpose of this example. )

A) Describe how a sample of data for testing the claim was obtained.

B) State the sample size, n, and what was recorded for each item in the sample. 

V) Verification of requirements, calculation of test statistic, statement of critical value(s).

Chapter 8-3 describes a number of ways to test the claim about the proportion given the sample data. For this assignment, use the Critical Value Method (p. 402).

A) First tell why the three requirements on the top of p. 400 are satisfied.

B) Calculate and show the test statistic.

VI) State the conclusion about the null hypothesis and then in words using the original claim.
