A population consists of the following five values: 19, 18, 10, 19, 12. Assume that samples of size 2 are randomly selected with replacement from this population. The first sample selected is 18, 18.
 
  What is the mean of the sampling distribution of means?
  A) 15.6 B) 19 C) 18 D) 15

Question 2

The numbers of books sold over the course of a four-day book fair were 182, 159, 223, and 86. Assume that samples of size 2 are randomly selected with replacement from this population of four values.
 
  List the 9 different possible samples and find the mean of each sample. Describe the sampling distribution of means.

Answer to Question 1

A

Answer to Question 2

Possible samples: 182-182; 182-159; 182-223; 182-86; 159-182; 159-159; 159-223; 223-86; 86-182; 86-159; 86-223; 86-86
Means: 182, 170.5, 202.5, 134, 170.5, 159, 191, 122.5, 202.5, 191, 223, 154.5, 134, 122.5, 154.5, 86
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.

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).
