According to a certain survey, adults spend 2.35 hours per day watching television on a weekday. Assume that the standard deviation for "time spent watching television on a weekday" is 1.93 hours. If a random sample of 50 adults is obtained, describe the sampling distribution of x overbar, the mean amount of time spent watching television on a weekday. One consequence of the popularity of the Internet is that it is thought to reduce television watching. Suppose that a random...

According to a 2011 report by the United States Department of Labor, civilian Americans spend 2.75 hours per day watching television. A faculty researcher, Dr. Sameer, at California Polytechnic State University (Cal Poly) conducts a study to see whether a different average applies to Cal Poly students. Suppose that for a random sample of 100 Cal Poly students, the mean and standard deviation of hours per day spent watching TV turns out to be 3.01 and 1.97 hours, respectively. The...

Suppose a study reported that the average person watched 4.35 hours of television per day. A random sample of 15 people gave the number of hours of television watched per day shown. At the 5% significance level, do the data provide sufficient evidence to conclude that the amount of television watched per day last year by the average person differed from the value reported in the study?

A recent research study reported that Americans spend an average of 3.6 hours on social media - per person per day. If the standard deviation for the number of hours of social media per day is 3 and a random sample of 145 Americans is selected for further study, answer the following questions about the sampling distribution: 1) The mean of this sample of n=145 belongs to a sampling distribution. What is the shape of this sampling distribution? 2) What...
