Answer

Explanation:

Step1: Calculate total frequency

$5 + 14+13 + 7+2=41$

Step2: Calculate relative frequency for A

Relative frequency of A = $\frac{5}{41}\times100%\approx12.20%$

Step3: Calculate relative frequency for B

Relative frequency of B = $\frac{14}{41}\times100%\approx34.15%$

Step4: Calculate relative frequency for C

Relative frequency of C = $\frac{13}{41}\times100%\approx31.71%$

Step5: Calculate relative frequency for D

Relative frequency of D = $\frac{7}{41}\times100%\approx17.07%$

Step6: Calculate relative frequency for F

Relative frequency of F = $\frac{2}{41}\times100%\approx4.88%$

Answer:

A. 12.20% B. 34.15% C. 31.71% D. 17.07% F. 4.88%
