Answer and explanation:
First, let's understand the difference between categorical and quantitative variables. A quantitative variable can also be called a numerical variable. As this name suggests, it involves numbers. It can be measured numerically and be used in calculations - this is important, because not everything that has numbers is used in calculations; take the zip code as an example. On the other hand, a categorical variable cannot be expressed numerically in the same way described above. It is related to a certain quality or characteristic of something. For instance, you can attribute the number one to a person who is sick and the number two to a person who is not sick. The numbers are just a representation of the qualities; they won't be used in calculations. Now, we can safely judge the options given:
The price in dollars of statistics textbooks. --> quantitative
The working status of a computer part (working/not working). --> categorical
The gender of faculty in the mechanical engineering department. --> categorical
The number of miles until failure of a certain brand of tires. --> quantitative
The political party affiliation of students at OSU. --> categorical
The time to complete an exam. --> quantitative
The shirt sizes of a running club. --> categorical

Explanation:
The Cello<span> is much larger and lower than the viola, and must be played while sitting with the instrument between the knees. Fortunately, cellos are made for students of all sizes.

The Violin<span> is the smallest, and is therefore the highest in pitch. It is also the most popular. It is played with the instrument under the chin while sitting or standing, and its small size makes it easily transporable.
