A table represents the number of students who passed or failed an aptitude test at two different campuses.

South Campus North Campus

Answer:

50 students

Explanation:

the answer is above

A frequency or oscillation is a number of cycles or completed alternations per unit time, and the calculation can be defined as follows:

Frequency calculation:

                       South Campus                      North Campus                  Total

Passed                    46                                           38                                 84

Failed                       54                                          62                                 116

Total                         100                                        100                              200

Following are the calculation of the expected frequency of south campus and Failed:

=(Total number of students at North Campus) ×(Total number of failed students)/ Total number of Students

  [tex]= \frac{(38+62)\times (54+62)}{(46+38+54+62)}\\\\= \frac{(100)\times ( 116)}{(84 +11 6)}\\\\= \frac{11600}{(200)}\\\\= \frac{116}{2}\\\\= 58\\\\[/tex]

The expected frequency for the north campus and failed is "58 students".
