Question

A recent article reported that a job awaits only one in three (0.33) new college graduates. The major reasons

given were an overabundance of college graduates and a weak economy. A survey of 200 recent graduates from your school revealed that 80 students had jobs. At the .01 significance level, can we conclude that a larger proportion of students at your school have jobs?

A.    The Null Hypothesis is:

a   Job awaiting new college graduates is           _______.


b  Job awaiting new college graduates is greater than _______.


c  Job awaiting new college graduates is less than        _______.


d Job awaiting new college graduates is not equal to     _______.


Answer the question by:

Selecting the appropriate letter and then entering the correct number for the Null Hypothesis.

Enter numerical value of the Null Hypothesis as a fraction or a 2 place decimal with a 0 to the left of the decimal point..

 

B.   The Alternate Hypothesis is:

a   Job awaiting new college graduates is equal to       ______.


b  Job awaiting new college graduates is greater than   ______.


c  Job awaiting new college graduates is less than      ______.

 

d  Job awaiting new college graduates is not equal to     ______.

Answer the question by:

Selecting the appropriate letter and then entering the correct number for the Alternate Hypothesis.

Enter numerical value of the Alternate Hypothesis as a fraction or a 2 place decimal with a 0 to the left of the decimal point..

 

 

C.   The appropriate distribution is:

a    Uniform Distribution

b   Normal Distribution

c    t Distribution

d    Chi Square Distribution


The Hypothesis test is a:

a    Left tail test

b    Right tail test

c    Two tail test


Enter the appropriate letters for answering the questions in the same order in which the questions are asked.

 

D.    Select and enter the letter for the appropriate decision rule.

       

Decision: rule

a    Ha hypothesis: If the Pvalue is equal to or greater than the significance level of the test.

b   Ha hypothesis: If the Pvalue is equal to or less than the significance level of the test.

c   Ho hypothesis: If the Pvalue is equal to or less than the significance level of the test.



 

E.    The numerical value of the test statistic is:

       Enter answer rounded to 1 decimal place.

 

F.   What is the Pvalue for the Hypothesis Test?

Enter answer as a decimal rounded to 3 places with a zero to the left of the decimal point.

Do not enter answer as a percent.

G.   Hypothesis Test Decision:


a    Null Hypothesis: Do not reject the null hypothesis. The data does not support the Alternate Hypothesis.


b   Alternate Hypothesis: Reject the null hypothesis. The data supports the Alternate Hypothesis.


c   Cannot be determined because the data set is a sample.


Enter the correct answer by selecting the appropriate letter.
