16-25 & 52 & 42 & 12 & 7 & 113 \\
\hline
26-35 & 33 & 50 & 5 & 9 & 97 \\

46-55 & 25 & 17 & 22 & 12 & 76 \\

\hline
\text{Marginal Total} & 180 & 126 & 70 & 70 & 446 \\

Note: A rating of good or excellent means the audience liked the movie, while a rating of poor means the audience disliked the movie.

Out of the total respondents, what percentage of respondents from the [tex]$46-55$[/tex] age group rated the film as excellent? Write your answer up to two decimal places.

Answer :

To find the percentage of respondents from the 46-55 age group who rated the film as "excellent," we will follow these steps:

1. Identify the relevant values from the table:
- The number of respondents in the 46-55 age group who rated the film "excellent" is 25.
- The total number of respondents in the 46-55 age group is 76.

2. Calculate the percentage:
- To find the percentage, use the formula:
[tex]\[
\text{Percentage} = \left(\frac{\text{Number of "excellent" ratings}}{\text{Total number of respondents in the group}}\right) \times 100
\][/tex]
- Plugging in the numbers:
[tex]\[
\text{Percentage} = \left(\frac{25}{76}\right) \times 100
\][/tex]

3. Final calculation:
- Calculate the division and then multiply by 100 to get the percentage:
[tex]\[
\text{Percentage} \approx 32.89
\][/tex]

So, the percentage of respondents from the 46-55 age group who rated the film as "excellent" is approximately 32.89%.
