Option A and C

Step-by-step explanation:

From the data given above, with a p value of 0.039 which is way less than 0.05, and with a less p value, the results are statistically significant and then we can reject the null hypothesis and conclude that the the is statistically significant evidence to show that the proportion of students with student loan debt does not equal 69%.
