# Random Sampling and Error

6.1

Consider the following data to be a population of N=20 values

______________________________________________________________

5 3 2 6 6 7 3 3 6 7

7 9 7 5 3 12 6 10 7 2

______________________________________________________________

a. Compute the population mean

b. A random sample of n=6 produced the following numbers: 6,12,10,3,2,2. Find the sample mean and determine the sampling error for this sample.

c. Find the range of extreme sampling error for a sample of 6. (Hint: Find the lowest possible sample mean and highest possible sample mean)
