THE NEXT QUESTIONS ARE BASED ON THE FOLLOWING INFORMATION:
A computer is programmed to draw 1000 samples,each of size 40 from a normally distributed population having mean 50 and standard deviation 10.For each sample,the mean and the median are computed.The average value and standard deviation of each set of estimates for the 1000 samples are as follows.
-Do the two statistics appear to be unbiased?
