I Died for Beauty

Hello people. Rather than watch the superbowl, I spent all day studying for a statistics quiz. Now, HOW THE HECK DOES ONE FIND THE T-VALUE IF ONE DOESN'T KNOW THE POPULATION MEAN?! To recap, the t-value is basically (sample mean - population mean) / standard error.

Also, we find the t-value when the standard deviation is NOT known, as opposed to finding the z score when the standard deviation IS known (which I know how to do.)

No, you are not doing my homework for me, you are just curing my brain before I bang it on something sharp and hard. I've spent all day on figuring out this stupid concept.
