The authors of a paper concluded that more boys than girls listen to music at high volumes. This conclusion was based on data from independent random samples of 770 boys and 749 girls from a country, age 12 to 19. Of the boys, 397 reported that they almost always listen to music at a high volume setting. Of the girls, 331 reported listening to music at a high volume setting. Do the sample data support the authors' conclusion that the...
