Question

ages number of students 15-18 7 19-22 7 23-26 7 27-30 9 31-34 7 35-38 9 based on the frequency distribution above, find the relative frequency for the class with lower class limit 27 relative frequency = % enter an integer or decimal number more.. give your answer as a percent, rounded to one decimal place submit question

Explanation:

Step1: Find total number of students

Sum the number of students in each class: \(7 + 7 + 7 + 9 + 7 + 9\)
\(= 7\times4 + 9\times2\)
\(= 28 + 18 = 46\)

Step2: Identify frequency for class 27 - 30

The frequency (number of students) for the class with lower limit 27 is 9.

Step3: Calculate relative frequency

Relative Frequency \(=\frac{\text{Frequency of class}}{\text{Total number of students}}\times100\%\)
\(=\frac{9}{46}\times100\%\)
\(\approx 19.6\%\) (rounded to one decimal place)

Answer:

19.6
