| Question 1069107:  A population consists of the following five values: 0, 0, 3, 5, 6.
 
 a.
 List all samples of size 3, and compute the mean of each sample. (Round sample means to 2 decimal places.)
 
 Sample	Values	  Sum	  Mean
 1        0, 0, 3
 
 2        0, 0, 5
 
 3        0, 0, 6
 4        0, 3, 5
 
 5        0, 3, 6
 6        0, 5, 6
 
 7        0, 3, 5
 
 8        0, 3, 6
 
 9        0, 5, 6
 
 10       3, 5, 6
 
 
 b.
 Compute the mean of the distribution of sample means and the population mean. (Round your answers to 1 decimal place.)
 
 
 Sample means
 
 Population mean

You can put this solution on YOUR website!  0, 0, 3	mean 1 0, 0, 5	mean 1.67
 0, 0, 6	mean 2
 0, 3, 5	mean 2.67
 0, 3, 6	mean 3
 0, 5, 6	mean 3.67
 0, 3, 5	mean 2.67
 0, 3, 6	mean 3
 0, 5, 6	mean 3.67
 3, 5, 6	mean 4.67
 Sum is 24+4.02=28.02
 Divided by 10, the mean of the 10 samples is 2.80
 The mean of the population 0,0,3,5,6 is 14/5=2.80
 All possible samples from a population with a given sample size will have a mean equal to the population mean.  We call that unbiased.
