(b)    What will be the value of population standard deviation if the size of the simple random sample is 25 and standard error of the mean is 2?                        

(c)    Why the Z test is usually inappropriate for small sample size?  Give reasons in support of your answer.                 

Question 2:                                                                                          Marks:4+6=10
