An experimenter wanted to test the hypothesis that a particular sample came from a population with a mean of 10. The sample had a mean of 8 and the standard error of the mean was .80. In order to test the experimenter's hypothesis with a t test, you would also need to know
A) µ
B) $\bar { X }$
C) $s _ { X }$
D) N.

To conduct a t-test, you need to know the sample size (N) along with the sample mean ($\bar{X}$), the population mean ($\mu$), and the standard error of the mean (which is derived from the sample standard deviation ($s_{X}$) and N). The question already provides $\mu$, $\bar{X}$, and the standard error, so the missing piece of information is the sample size (N).
