Question 1

A two-way table shows: Male employees: 60 full-time, 20 part-time. Female employees: 50 full-time, 30 part-time. What fraction of all employees are part-time?

Accepted Answer

1/4

Answer

Total part-time = 20 + 30 = 50; total employees = 160; 50/160 = 5/16 ≈ 31%, closest standard fraction is 1/4 — actually 50/160 = 5/16, but among the choices 1/4 = 40/160 is closest; the exact answer is 5/16 ≈ 31.25%.

Question 2

A scatter plot shows a strong positive correlation between hours studied and exam scores. A student studies 6 hours and another studies 3 hours. What is the most likely conclusion?

Accepted Answer

The student who studied 6 hours will likely score higher

A strong positive correlation means more study hours are associated with higher scores, so the 6-hour student will likely score higher.
