Question
Use the following scenario to answer the question.
Topic: Sampling. (Ch. 7) Scenario: The following are recorded values of snowfall (in inches) during the entire year at sixteen ski resorts:
64 62 41 50 49 47 33 72 52 40 76 50 26 36 36 57
Which of the following is true?
A) Sampling error is not influenced by sample size
B) A sample including all values in the top row and the first four values of the second row should result in a sampling error greater than 2.9
C) A sample including all values in the top row and the first four values of the second row should result in a sampling error less than 2.9
D) None of the above statements are true
Explanation / Answer
sample including all values in the top row and the first four values of the second row.
Sample are 64, 62, 41, 50, 49, 47, 33, 72, 52, 40, 76, 50
Standard Error= sd/ Sqrt(n)
Where,
sd = Standard Deviation
n = Sample Size
Standard deviation( sd )=13.0593
Sample Size(n)=12
Standard Error = ( 13.0593/ Sqrt ( 12) )
= 3.77
[ANSWER]
B) A sample including all values in the top row and the first four values of the second row should result in a sampling error greater than 2.9
