Question: MyTube com tells its advertisers that 45 of its users
MyTube. com tells its advertisers that 45% of its users are in the 17 to 25 age demographic, 35% are in the 26 to 45 demographic, and the remaining 20% are in the 46 and older demographic. Perkins Music, one of the website’s advertisers, conducted a survey of 200 randomly selected MyTube users. In the Perkins sample, 98 users were in the 17 to 25 age demographic, 62 were in the 26 to 45 demographic, and the rest were in the 46 and older demographic. Conduct a proper hypothesis test to determine whether this sample result is enough to reject a null hypothesis that the age group distribution of MyTube.com users is as MyTube.com describes. Use a significance level of .05.
