We are given:
Yes No
Junior 150 210
Senior 112 200
A) We determine the total number of students polled:
$$\displaystyle{150}+{210}+{112}+{200}={672}\frac{=}{{360}}$$
B) We check if a senior is more likely to be planning on a scientific major than a nonscientific major: $$\displaystyle\frac{{112}}{{>}}{200}$$
C) We check if a student planning on a scientific major is more likely to be a junior than a senior: $$\displaystyle{150}{>}{112}$$
D) We check if more seniors than juniors plan to enter a scientific field to study: $$\displaystyle\frac{{112}}{{>}}{150}$$
The true statement is C.
