How to compute the test statistic?
Okay, thanks for explaining. Can you give me an example calculation for a t-test?
Sure. Let's say your sample mean is 7, the hypothesized population mean is 5, the sample standard deviation is 2, and the sample size is 30. The difference between the sample mean and the hypothesized population mean is 2. The standard error of the mean is 0.365. Dividing the difference by the standard error gives a t-value of 5.48.
