The four members of a gymnastics team are Laura, Tara, Maura, and Flora. Their heights are 60, 60, 62, 59 respectively. Assume that samples of size 2 are randomly selected with replacement from this population.
 
  List the 16 different possible samples and find the mean height of each sample. Find the sampling distribution of means. Find the mean of the sampling distribution.

Answer to Question 1

Possible samples: Laura-Laura, Laura-Tara, Laura-Maura, Laura-Flora, Tara-Laura, Tara-Tara, Tara-Maura, Tara-Flora, Maura-Laura, Maura-Tara, Maura-Maura, Maura-Flora, Flora-Laura, Flora-Tara, Flora-Maura, Flora-Flora

Sample means: 60, 60, 61, 59.5, 60, 60, 61, 59.5, 61, 61, 62, 60.5, 59.5, 59.5, 60.5, 59
The probability of each sample is 1/16 so the sampling distribution consists of the 16 sample means paired with the probability of 1/16.
Mean of the sampling distribution is 60.25 inches.

Answer to Question 2

B
