Suppose you have a sample from a population with a normal distribution with mean 0 and variance 1. What happens when you increase the mean and why? What happens when you increase the variance and why? What happens if you increase the sample size and why?
If the mean is increased keeping the variance the same, the bell shaped curve shifts towards the right but the shape of the curve (i.e., the spread of the ...
Analyze normal distribution and variance in the case.
