Group Questions
Information
While you are required to work together on this quiz, each member of the group must submit his or her
own answers in order to receive credit.
If needed, here's a link to the Normal Probability Applet.
When calculating anything, please remember to round to three decimal places, unless otherwise
specified. DO NOT ROUND until your calculation is complete.
Question 3 point
Use the normal probability applet to find the combined area under the standard normal curve that is to the
right of z = 1.358 and to the left of z = -1.358. (Round your answer to 3 decimal places. Example: If the
answer is 0.8976 then you would enter 0.898 in the answer box.)

, Which of the following will have a smaller standard deviation, if nine observations are randomly drawn
from a population?
Question options:
The distribution of the individual observations, XX {"version":"1.1","math":"X"} .
The distribution of the sample means, X¯X¯ {"version":"1.1","math":"\bar X"} .
This cannot be determined from the information given.
Question
point
5
Which of the following results implies that the spread in x¯x¯ {"version":"1.1","math":"\bar x"} decreases
as the sample size increases?
Question options:
The normal distribution.
The 68-95-99.7% Rule.
The Central Limit Theorem.
The Law of Large Numbers.
Information
Use the following information to answer the next 4 questions.
Scores on the quantitative portion of the GRE are approximately normally distributed with mean
μ=150.8μ=150.8 {"version":"1.1","math":"\mu = 150.8 "} and standard deviation σ=8.8σ=8.8
{"version":"1.1","math":"\sigma = 8.8"} . (1)
