self-quiz to gage the student’s anxiety. The score for 30 students are given
here.

1. Construct
a frequency table with class, frequency, relative percent, and cumulative
percent that has 6 classes to describe the distribution of the data in SPSS.

2. Use
the frequency table created in problem to construct a histogram in SPSS.

3. Use
SPSS to calculate the numerical descriptive statistics mean, median, standard
deviation, and variance of the anxiety scores.

assignment.

not required for the body of this assignment, solid academic writing is
expected, and documentation of sources should be presented using APA formatting
guidelines, which can be found in the APA Style Guide, located in the Student

There are many misconceptions about probability
which may include the following.

·
All
events are equally likely

·
Later
events may be affected by or compensate for earlier ones

·
When
determining probability from statistical data, sample size is irrelevant

·
Results
of games of skill are unaffected by the nature of the participants

·
“Lucky/Unlucky”
numbers can influence random events

·
In
random event involving selection, results are dependent on number rather than
rations

·
If
events are random then the results of a series of independent events are
equally likely

The following statements are all incorrect. Explain
the statements and the errors fully using the probability rules discussed in
topic two.

1. I
have flipped and unbiased coin three times and got heads, it is more likely to
get tails the next time I flip it.

2. The
Rovers play Mustangs. The Rovers can win, loose, or draw, so the probability
that they win is 1/3.

3. I
roll two dice and ad the results. The probability of getting a total of 6 is
1/12 because there are 12 different possibilities and 6 is one of them.

4. Mr.
Purple has to have a major operation. 90% of the people who have this operation
make a complete recovery. There is a 90% chance that Mr. Purple will make a
complete recovery if he has this operation.

5. I
flip two coins. The probability of getting heads and tails is 1/3 because I can
get Heads and Heads, Heads and Tails, or Tails and Tails.

6. 13
is an unlucky number so you are less likely to win raffles with ticket number
13 than with a different dumber.

A researcher randomly assigns 33 subjects to one of
three groups. Group 1 receives technical dietary information interactively from
an on-line website. Group 2 receives the same information from a nurse
practitioner, while Group 3 receives the information from a video tape made by
the same nurse practitioner.

The researcher looked at three different ratings of
the presentation; difficulty, usefulness, and importance to determine if there
is a difference in the modes of presentation. In particular, the researcher is
interested in whether the interactive website is superior because that is the
most cost-effective way of delivering the information.

statistical notation) need to address the research question.

Choose which statistical test would be used to conduct the
study and support it with research.

Describe the type of data needs to be collected to conduct
the study and what techniques are best for collecting data.

Use three to five scholarly resources to support your
explanations.
