Question
Please show the “BELL CURVE” model and any “HYPOTHESIS TEST GRAPH GENERATOR” and “EVERY STEP” you took to solve the problem “WITHOUT TAKING ANY SHORT CUTS” so I can see every step to solve the problem. When short cuts are taken, it is hard to determine what the missing step was.
2) Determine the critical value(s) of the test statistic for each of the following small samples
