Answer:

C.It is a​ one-tailed test since the alternative hypothesis states that the parameter is greater than the hypothesized value.

Step-by-step explanation:

Let p be the percentage of students enrolled in an introductory Chemistry class dropped before the midterm. Then null and alternative hypotheses are:

H_{0}: p=10%

H_{a}: p>10%

The alternative hypothesis states that the parameter is greater than the hypothesized value.
