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
