... Independence of measurement means that making one measurement will tell you nothing about any of the other measurements you make. This is essentially why we want truly random sampling when we are doing statistics (if possible). When two events are statistically independent, it means that knowing whe ...

The test had a mean of 50 and a standard deviation of 5.What is the probability that a randomly selected student achieved a higher score? We need to find the probability that a value greater than 56 is selected from a no ...
