Question

60% of students entering four-year colleges receive a degree within six years. Is this percent larger than for students who play intramural sports? 126 of the 204 students who played intramural sports received a degree within six years. What can be concluded at the level of significance of αα = 0.10?

  1. For this study, we should use Select an answer z-test for a population proportion t-test for a population mean 
  2. The null and alternative hypotheses would be:    
     Ho: ? p μ  Select an answer = < > ≠   (please enter a decimal)   
     H1: ? p μ  Select an answer ≠ < = >   (Please enter a decimal)
  1. The test statistic ? z t  =  (please show your answer to 3 decimal places.)
  2. The p-value =  (Please show your answer to 4 decimal places.)
  3. The p-value is ? ≤ >  αα
  4. Based on this, we should Select an answer fail to reject accept reject  the null hypothesis.
  5. Thus, the final conclusion is that ...
    • The data suggest the populaton proportion is significantly larger than 60% at αα = 0.10, so there is sufficient evidence to conclude that the population proportion of students who played intramural sports who received a degree within six years is larger than 60%
    • The data suggest the population proportion is not significantly larger than 60% at αα = 0.10, so there is sufficient evidence to conclude that the population proportion of students who played intramural sports who received a degree within six years is equal to 60%.
    • The data suggest the population proportion is not significantly larger than 60% at αα = 0.10, so there is not sufficient evidence to conclude that the population proportion of students who played intramural sports who received a degree within six years is larger than 60%.
  6. Interpret the p-value in the context of the study.
    • If the sample proportion of students who played intramural sports who received a degree within six years is 62% and if another 204 students who played intramural sports are surveyed then there would be a 30.35% chance of concluding that more than 60% of all students who played intramural sports received a degree within six years.
    • There is a 30.35% chance that more than 60% of all students who played intramural sports received a degree within six years.
    • If the population proportion of students who played intramural sports who received a degree within six years is 60% and if another 204 students who played intramural sports are surveyed then there would be a 30.35% chance that more than 62% of the 204 students surveyed received a degree within six years
    •  There is a 30.35% chance of a Type I error.
  7. Interpret the level of significance in the context of the study.
    • There is a 10% chance that aliens have secretly taken over the earth and have cleverly disguised themselves as the presidents of each of the countries on earth.
    • There is a 10% chance that the proportion of all students who played intramural sports who received a degree within six years is larger than 60%.
    • If the population proportion of students who played intramural sports who received a degree within six years is 60% and if another 204 students who played intramural sports are surveyed then there would be a 10% chance that we would end up falsely concluding that the proportion of all students who played intramural sports who received a degree within six years is larger than 60%
    • If the population proportion of students who played intramural sports who received a degree within six years is larger than 60% and if another 204 students who played intramural sports are surveyed then there would be a 10% chance that we would end up falsely concluding that the proportion of all students who played intramural sports who received a degree within six years is equal to 60%.
