Instruction
An experiment was conducted on randomly selected Fraser students: each student sees a photo of an object (visual) and then identifies the object, and each student hears a sound (auditory) and then identifies the sound.
Questions 9-16) is about the population proportion () of Fraser students who have jobs.
Question 9 -16
The variable "Job" indicates whether a student has a job or not. "Y" means the student has a job where they are required to work more than 5 hours per week, and "N" means the student does not have this type of job. A researcher wants to see if the population proportion of students with jobs at Purdue is different from 0.59. Use = 0.05.
Q9. Define the parameter using context
Q10. State the hypotheses for this test, using the correct parameter, signs, and hypothesized value
Q11. Compute , the point estimate for the population proportion
- Estimate the proportion of students with jobs by dividing the number of observed "Y"s by the sample size.
- Find the name and value of the point estimate, rounded to 4 decimals.
Q12. Is the Normality condition in place for your data?
- Find the correct values to confirm that this condition is valid: 0 5 and (1 0) 5
Q13. Compute the test statistic.
- Round and standard error to 3 decimals
- State the name of the test statistic, and the computed value, rounded to 2 decimals.
Q14. Find the p-value using a table: Type the probability statement for the p-value for the computed test statistic and the approximate probability found using the appropriate table.
Q15. Find the critical value(s) for the rejection region for this test.
Q 16. After comparing the p-value to , or the test statistic to the critical value, type the conclusion.
