a sample of 335 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. among the male students in the sample, find the relative frequency of those who happen to major in business. round your answer to two decimal places.

Explanation:

Step1: Calculate total male students

$34 + 29+47 + 46+46=202$

Step2: Calculate relative - frequency of male business majors

The number of male business majors is 29. The relative frequency $=\frac{29}{202}\approx0.14$
