Solution:

Viewer's Age Group ExcellentGood Average Poor Total

16-25: 52 42 12 7 113

26-35 33 50 5 9 97

36-45 58 12 28 34 132

46-55 25 17 22 12 76

56 and Above 12 5 3 8 28

Marginal Totals 180 126 70 70 446

% of people who liked the movie (rating of good or excellent)= $\frac{180+126}{446}\times100=\frac{306}{446}\times 100=68.60$

% of people who Disliked the movie (rating of Poor)= $\frac{70+70}{446}\times100=\frac{140}{446}\times 100=31.40$ %

% of people in the age group(16-25) liked the movie (rating of good or excellent)= $\frac{52+42}{113}\times100=\frac{94}{113}\times 100=83.18$ %

% of people age group(16-25) who Disliked the movie (rating of Poor)=100-83.18=16.82%

% of people in the age group(26-35) liked the movie (rating of good or excellent)= $\frac{50+33}{97}\times100=\frac{83}{97}\times 100=85.56$ %

% of people age group(26-35) who Disliked the movie (rating of Poor)=100-85.56=14.44%

% of people in the age group(36-45) liked the movie (rating of good or excellent)= $\frac{58+12}{132}\times100=\frac{70}{132}\times 100=53.03$ %

% of people age group(36-45) who Disliked the movie (rating of Poor)=100-53.03=46.97%

% of people in the age group(46-55) liked the movie (rating of good or excellent)= $\frac{25+17}{76}\times100=\frac{42}{76}\times 100=55.26$ %

% of people age group(46-55) who Disliked the movie (rating of Poor)=100-55.26=44.74%

% of people in the age group(55 and above) liked the movie (rating of good or excellent)= $\frac{12+5}{28}\times100=\frac{17}{28}\times 100=60.71$ %

% of people age group(55 and above) who Disliked the movie (rating of Poor)=100- 60.71=39.29%
