College of St Joseph A Nationwide Survey Discussion Post
I’m working on a statistics discussion question and need support to help me understand better.
- Use google to find a problem for a hypothesis test for one proportion such as the one below. (It is the same one as the introduction) Make sure you solve your own problem this week… I need the information.
Example- How cool is Facebook? In a recent GenX2Z American College Student Survey, 90% of female college students rated the social network site Facebook as “cool.” The other 10% rated it as “lame.” Assume that the survey was based on a sample of 500 students. A marketing executive at Facebook wants to advertise the site with the slogan “More than 85% of female college students think Facebook is cool.” Can he conclude that the proportion of female college students who think Facebook is cool is greater than 0.85?
2 .Pick another student’s problem and solve it. Make sure to include your null and alternative hypothesis, your test statistic, your p-value, decision, and conclusion in the context in your response.
Another student problem : Game consoles: A poll taken by the Software Usability Research Laboratory surveyed 341 video gamers, and 110 of them said that they prefer playing games on a console, rather than a computer or hand-held device. An executive at a game console manufacturing company claims that more than 25% of gamers prefer consoles. Does the poll provide convincing evidence that the claim is true? Use the ? = 0.01 level of significance.
Student problem should be this : A nationwide survey of working adults indicates that only 50% of them are satisfied with their jobs. The president of a large company believes that more than 50% of employees at his company are satisfied with their jobs. To test his belief, he surveys a random sample of 100 employees, and 54 of them report that they are satisfied with their jobs. Can he conclude that more than 50% of employees at the company are satisfied with their jobs? Use the ? = 0.05 level of significance.
