A recent study of debt among college graduates reported that the average debt accumulated by graduates of private colleges was $38,200, with a sample standard deviation of $2,054, while the average debt accumulated by graduates of public colleges was $11,700, with a sample standard deviation of $2,075. The sample sizes were 70 and 180, respectively. Complete parts a and b below. Conduct a hypothesis test to determine if the average college debt for bachelor of arts degree recipients is at least $21,000 more for graduates from private colleges than from public colleges.

d. State the conclusion for this hypothesis test. O A. Do not reject Ho. There is sufficient evidence at the a= 0.025 level of significance to conclude that graduates of private colleges have at least $21,000 more in college-related debt. B. Reject Ho. There is not sufficient evidence at the a = 0.025 level of significance to conclude that graduates of private colleges have at least $21,000 more in college-related debt. OC. Reject Ho- There is sufficient evidence at the a = 0.025 level of significance to conclude that graduates of private colleges have at least $21,000 more in college-related debt. D. Do not reject Ho. There is not sufficient evidence at the a = 0.025 level of significance to conclude that graduates of private colleges have at least $21,000 more in college-related debt.
