The following are the heights of four students in centimeters. Suppose samples of size 2 are taken from this population of four students.
Question: How many samples are possible? List and compute the mean of each sample.
Let the height of four students be 152, 156, 160, and 164 cm
Sample of size 2 to be taken
So, there will be "^4C_2 = 6" samples of size 2
Samples:
(152,156), (152,160), (152,164), (156,160), (156,164), (160,164)
Mean of each samples:
154 , 156 , 158 , 158 , 160 , 162
