Suppose That in the Population of American College Students the Average

Question

Examlex · Accepted Answer

The Answer is So I do not know the population standard deviation here, which means I'll have to look in Appendix B using the t values. First, I must calculate a standard error of the mean:

S_{\bar{x}}

= 4/? 16

\rightarrow

4/4

\rightarrow

1.
Next I calculate a t value: t = 10 - 12/1 = -2/1 = -2.00.
My degrees of freedom will be 16 = 1 = 15.
So in Appendix B, looking at 15 degrees of freedom I find a value of 1.753 and a value of 2.131. These are the two closest values to 2.00. Then I look up at the top of the table and find that these correspond with alpha levels of .10 and .05. So the best I can do is say that the probability of getting a sample mean of 10 from this population, when the sample is randomly selected and n = 16, is between 5% and 10%.
