• Distribution of Sample Means
• Calculating Standard Error

"Myra," said Jason, "this is where my knowledge of statistics is a little weaker than yours. I'm still not sure how we can use thissampleto make a statementabout the sleeping habits of an entire population of working college students."

"Look Jason," Myra replied. "Here is the stack of survey responses. Pick out five of them at random, and then make a list of them ona sheet of paper."

When Jason was finished, his list looked like this:

Subject #12:6 hours

Subject #23:6.5 hours

Subject #49:6.5 hours

Subject #82:7.5 hours

Subject #98:5 hours

"Let's consider thesefive asthe population," said Myra. "Now, all ten samples of the size n = 2 can be taken, and the sample means can be found. For example, the mean of the first two subjects is 6.25 hours of sleep. The Central Limit Theorem tells us that distributions with a finite mean and standard deviation, the distribution of the sample means is approximately normal for large sample size. "

Using the data from the 5 students above, the mean of these sample means is (A) __________, and the standard errorof the sample meanis (B) __________.
