I just didn't know enough about this student t distribution thing. I saw the formula in Wikipedia and it seemed like the only variables were v (degrees of freedom) and t, and I read somewhere that you specify the degrees of freedom, therefore I thought you need to solve for t, but now I see that you specify a value for t also (so there are really two inputs) and then the value you are looking for is the whole expression with t and v plugged in. So X = (the whole expression) and solve for x. But I've already removed my equation from my 17b after I saw your work and Dieter's work. |
