What assumption must hold to make statistical inferences about a population variance?
Assume that a random sample of nine measurements from a normally distributed population gives a sample mean of (xbar = 2.57) and a sample standard deviation of s=.3. Use critical values to test H0:u=3 versus Ha:u?3 using levels of significance a=.
