Is this percent different from for students who play intramural sports? 120 of the 236 students who played intramural sports received a degree within six years. What can be concluded at the level of significance of a = 0.05? a. For this study, we should use | z-test for a population proportion b. The null and alternative hypotheses would be: Ho: P VE (please enter a decimal) H, : PVC (Please enter a decimal) C. The test statistic [z (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is ~ a f. Based on this, we should fail to reject Vy the null hypothesis. g. Thus, the final conclusion is that ... OThe data suggest the population proportion is not significantly different from 55% at a = 0.05, 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 55%. The data suggest the populaton proportion is significantly different from 55% at a - 0.05, 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 different from 55% The data suggest the population proportion is not significantly different from 55% at a = 0.05, 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 different from 55%.
