QUESTION 3 Consider a small population of N = 7 units, labeled a .b.c, d, e, f and g with respective y- values 2, 3, 4, 5, 6 and 7 and 8. Consider a simple random sample design with a sample size n= 7 drawn without replacement. List every possible sample of size n=5. Demonstrate numerically that the sample mean is unbiased estimator for the population mean. Determine numerically whether the sample median is also unbiased estimator for the population median or not. Verify numerically whether E(s) - where s is the sample variance from the Check numerically whether Esmo? where sm' is the sample variance from the median mean. .
