Question

For this study, we should use Select an answer z-test for a population proportion t-test for a population mean
The null and alternative hypotheses would be:
Ho: ? μ p Select an answer ≠ < = > (please enter a decimal)
H₁: ? p μ Select an answer > = < ≠ (Please enter a decimal)

The test statistic ? z t = (please show your answer to 3 decimal places.)
The p-value = (Please show your answer to 4 decimal places.)
The p-value is ? ≤ > αα
Based on this, we should Select an answer fail to reject reject accept the null hypothesis.
Thus, the final conclusion is that ...
- The data suggest the population proportion is not significantly larger than 51% at αα = 0.01, 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 51%.
- The data suggest the population proportion is not significantly larger than 51% at αα = 0.01, 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 51%.
- The data suggest the populaton proportion is significantly larger than 51% at αα = 0.01, 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 51%
Interpret the p-value in the context of the study.
- If the population proportion of students who played intramural sports who received a degree within six years is 51% and if another 271 students who played intramural sports are surveyed then there would be a 2.75% chance that more than 57% of the 271 students surveyed received a degree within six years
- If the sample proportion of students who played intramural sports who received a degree within six years is 57% and if another 271 students who played intramural sports are surveyed then there would be a 2.75% chance of concluding that more than 51% of all students who played intramural sports received a degree within six years.
- There is a 2.75% chance that more than 51% of all students who played intramural sports received a degree within six years.
- There is a 2.75% chance of a Type I error.
Interpret the level of significance in the context of the study.
- There is a 1% chance that the proportion of all students who played intramural sports who received a degree within six years is larger than 51%.
- If the population proportion of students who played intramural sports who received a degree within six years is larger than 51% and if another 271 students who played intramural sports are surveyed then there would be a 1% 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 51%.
