Question
60% of students entering four-year colleges receive a degree within six years. Is this percent smaller than for students who play intramural sports? 130 of the 241 students who played intramural sports received a degree within six years. What can be concluded at the level of significance of a = 0.01? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho:1?v Но: 7Select an answer v (please enter a decimal) H1:1?v|Select an answer v (Please enter a decimal) c. The test statistic ? (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 ? va f. Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusiion is that .. The data suggest the population proportion is not significantly smaller than 60% at a = 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 smaller than 60%. The data suggest the populaton proportion is significantly smaller than 60% at a = 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 smaller than 60% %3D The data suggest the population proportion is not significantly smaller than 60% at a = 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 60%. h. 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 60% and if another 241 students who played intramural sports are surveyed then there would be a 2.74 chance fewer than 54% of the 241 students surveyed received a degree within six year5.
