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 762 boys and 746 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 proportion of the country's boys who listen to music at high volume is greater than this proportion for the country's girls? Test the relevant hypotheses using a 0.01 significance level. (Use a statistical computer package to calculate the P-value. Use Pboys-Pgirls. Round your test statistic to two decimal places and your P-value to four decimal places.) z= P-value = State your conclusion. ○ we fail to reject Ho. We don't have convincing evidence that the proportion of the country's boys who listen to music at high volume is greater than the proportion of the country's girls who listen to music at high volume. ○ we fail to reject Ho.
