Question

a sample of 326 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.

what is the relative frequency of male students in the sample?
round your answer to two decimal places.

Explanation:

Step1: Calculate the number of male students

Add up the male - student numbers in each major: \(41 + 24+22 + 44+43=174\)

Step2: Calculate the relative frequency

The formula for relative frequency is \(\text{Relative Frequency}=\frac{\text{Number of male students}}{\text{Total number of students}}\). The total number of students is \(326\). So, \(\text{Relative Frequency}=\frac{174}{326}\approx0.53\)

Answer:

\(0.53\)
