Question 7 | Mathematics homework help

A recent article in USA today reported that a job awaits only 1 in 3 (33.3%) 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 a .05 significance level, can we conclude that a larger proportion of students at your school have jobs?

 

What is the null hypothesis for this hypothesis test?

 

a The number of students that had jobs is less than 33.3% b The number of students that had jobs is more than 33.3% c The number of students that had jobs is less than or equal to 33.3%. d The number of students that had jobs is more than or equal to 33.3% e The number of students that had jobs is not equal to 33.3%

 

Enter the correct answer by selecting the appropriate letter without a decimal point.

 

___c___

 

What is the alternate hypothesis for this hypothesis test?

 

a The number of students that had jobs is less than 33.3% b The number of students that had jobs is more than 33.3% c The number of students that had jobs is less than or equal to 33.3%. d The number of students that had jobs is more than or equal to 33.3% e The number of students that had jobs is not equal to 33.3%

 

Enter the correct answer by selecting the appropriate letter without a decimal point.

 

___b___

 

What is the significance level of the test?

 

Enter answer as a 2 place decimal with a 0 entered to the left of the decimal point. Do not enter answer as a percent.

 

___0.05___

 

What is the appropriate distribution to use to answer the question?

 

a Uniform Distribution b Normal Distribution c t Distribution d Chi Square Distribution e F Distribution

 

Enter the correct answer by selecting the appropriate letter without a decimal point.

 

___b___

 

What is the numerical value of the test statistic? Enter answer as a decimal rounded to 1 or less places (1 place or an integer which ever is appropriate)?

 

___2.1___

 

What is the numerical value of the Pvalue?

 

Enter answer rounded to 2 places with a zero to the left of the decimal place. Do not enter answer as a percent.

 

___0.40__

 

What is the Pvalue Decision Rule?

 

a. The data supports the alternate hypothesis if the Pvalue is greater than the significant level of the test. b. The data supports the alternate hypothesis if the Pvalue is less than or equal to the significant level of the test. c. The data supports the alternate hypothesis if the Pvalue equals the significant level of the test. d. The data supports the alternate hypothesis if the Pvalue does not equal the significant level of the test.

 

Select the correct answer and enter the appropriate letter without a decimal point.

 

___A__

 

What is the appropriate decision based upon your analyses of the data? Enter the correct answer by selecting the appropriate letter without a decimal point.

 

a There is sufficient evidence reject the null hypothesis. b There is insufficient evidence to reject the null hypothesis. c There is insufficient evidence to make a decision based upon the data.

 

Enter the correct answer by selecting the appropriate letter without a decimal point.
