What percentage of the audience from the 16-25 age group gave the movie a poor rating?

A. [tex]$6.19 \%$[/tex]
B. [tex]$25.34 \%$[/tex]
C. [tex]$15.70 \%$[/tex]
D. [tex]$16.22 \%$[/tex]

Answer :

We start by noting that for the age group 16–25 there are 113 viewers in total, and out of these, 7 viewers rated the movie as poor.

The percentage of viewers from the 16–25 age group who gave the movie a poor rating is calculated using the formula:

[tex]$$
\text{Percentage} = \left(\frac{\text{Number of poor ratings}}{\text{Total viewers in the age group}}\right) \times 100
$$[/tex]

Substituting the given numbers:

[tex]$$
\text{Percentage} = \left(\frac{7}{113}\right) \times 100 \approx 6.19\%
$$[/tex]

Thus, approximately [tex]$6.19\%$[/tex] of the audience in the 16–25 age group gave the movie a poor rating.
