For students who first_enrolled in two-year public institutions in a recent semester, the proportion who earned a bachelor's degree within six years was 0.389 . The president of a certain junior college believes that the proportion of students who enroll in her institution have a higher completion rate. (b) State the hypotheses symbolically. (Type integers or decimals. Do not round.)

Step 1 ：The question is asking for the hypotheses in a statistical test. We are testing the claim that the proportion of students who enroll in the president's institution have a higher completion rate than the general proportion of 0.389.

Step 2 ：The null hypothesis (H0) is that the proportion of students who complete their degree in the president's institution is equal to the general proportion of 0.389.

Step 3 ：The alternative hypothesis (Ha) is that the proportion of students who complete their degree in the president's institution is greater than the general proportion of 0.389.

Step 4 ：Final Answer: The null hypothesis, \(H0: p = 0.389\). The alternative hypothesis, \(Ha: p > 0.389\).
