Answer:
Explanation:
To determine the relative frequencies, we need to calculate the percentage of each period's student count out of the total number of students.The total number of students can be found by summing the counts of all periods:Total students = 25 + 14 + 21 + 18 = 78Now, let's calculate the relative frequencies for each period:Period 1: (25/78) * 100% ≈ 32.05%
Period 2: (14/78) * 100% ≈ 17.95%
Period 3: (21/78) * 100% ≈ 26.92%
Period 4: (18/78) * 100% ≈ 23.08%The percentages rounded to the nearest whole number are approximately:
Period 1: 32%
Period 2: 18%
Period 3: 27%
Period 4: 23%Comparing these percentages to the given options, we can see that option C. 32%, 18%, 27%, 23% best describes the relative frequencies of the student counts.
