Let x_(1),x_(2),dots,x_(n) be the independent normal random variables having mean mu and variance sigma ^(2).
For each question, write the distribution name (e.g. Normal, chi ^(2),t,F ) and find the value(s) of the
distribution parameter(s). Explain why it follows the distribution you identified.
For a normal distribution, write the mean and variance. For other distributions, find the value(s)
of degree(s) of freedom.
Find the distribution of x_(i) for i=1,dots,n.
Find the distribution of sum_(i=1)^n x_(i).
Find the distribution of ar{x} .
Let X1, X2,..., X, be the independent normal random variables having mean and variance 2 For cach qucstion, write the distribution name (c.g. Normal,2, t, F) and find the values) of the distribution parameter(s). Explain why it follows thc distribution you identified. For a normal distribution, write the mean and variance. For other distributions, find the value(s of degree(s) of freedom.
