Answer:

Inferential study

Step-by-step explanation:

From the question, we understand that the professor concluded that majority of the class (of 198 students) preferred in class assessment based on the response from 67% of the sample size (i.e 30 students)

When decisions or conclusions are made about an overall population based on a survey carried out on a smaller sample, such study is referred to as an inferential study or inferential research.

Descriptive study on the other hand focuses on the features rather than the result of the experiment of the dataset.
