    Probability of type 1/type 2 errors and distribution of p-values

    Hi, I had a statistics exam today and there were three questions about which I felt a little uneasy. The questions which felt too easy involved finding the probability of type 1 and type 2 errors. The scenario was that a lie detector test was given to 1000 people. Of those 1000 people, 500...

    Matrices: Number of solutions of Ax=c if we know the solutions to Ax=b

    Hey guys, Here is my question. A is a 4x4 matrix and there are two vectors, b and c, which have 4 real numbers. If we are told that A(vector x)=(vector b) has an unique solution, how many solutions does A(vector x)=(vector c) have? I honestly have no idea how to do this. I know that for A...
