Question

A sample of 369 students at a university is surveyed. The students are classified according to gender ("female" or "male"). They are also classified according to major ("biology", "business", "engineering", "mathematics", or "computer science"). The results are given in the contingency table below.

Answer 1

Answer:

Relative frequency of business major in the sample = 0.23

Explanation:

Total number of students surveyed = 369

Total number of students offering business major = 39 + 47

Total number of students offering business major = 86

Relative frequency =

(Total number of students offering business major)/(Total number of students surveyed)

Relative frequency of business major in the sample = 86/369

Relative frequency of business major in the sample = 0.23
