Question 360671: Americans watch an average of 4.0 hours of television per day with a standard deviation of 2.1 hours per day. Let's say we would pick many, many random samples of 100 Americans, and find the mean number of hours watched for each sample. These sample means would create a sampling distribution for the sample mean. According to the Central Limit Theorem, what would be the shape, the mean, and the standard deviation of this sampling distribution?
A. The shape would be approximately normal because n > 30. The mean would be 4.0 hours, and the standard deviation would be 0.21 hours.
B. The shape would be approximately normal because n > 30. The mean would be 4.0 hours, and the standard deviation would be 2.1 hours.
C. The shape would be exactly normal because n > 30. The mean would be 4.0 hours, and the standard deviation would be 0.21 hours.
D. The shape would be approximately normal because n > 30. The mean would be 0.4 hours, and the standard deviation would be 0.21 hours.
