PART
I: SHORT RESPONSEDirections: Please answer each of the following questions thoroughly.1. For each of several
randomly selected years, the total number of points scored in the Super Bowl
football game and the total number of new cars sold in the United States are
recorded.a.
For this sample of paired data,
what does r represent? b.
What does ? represent? c.
Without doing any research or
calculations, estimate the value of r. 2. What is meant by the
statement that correlation does not imply causality?3. Describe
the error in the stated conclusion for each statement.a. Given:
There is a linear correlation between the number of cigarettes smoked each day
and the pulse rate, so that more smoking is associated with a higher pulse
rate.Conclusion: Smoking causes an increase in
the pulse rate.b. Given:
There is a linear correlation between annual personal income and years of
education.Conclusion: More education causes a person’s
income to rise.4. A jeweler at Tiffany
& Company computes the value of the linear correlation coefficient for
pairs of sample data consisting of Tiffany prices for gold wedding rings and
the corresponding prices at a discount store.
She obtains a value of r = 1 and concludes that the prices at
both companies are the same. Is she correct? Why or why not?5. Use
the given data below to find the best predicted value of the response variable.
Be sure to follow the prediction procedure summarized in Figure 10-5 in your
textbook.a. In a study conducted by University
of Arizona researchers, the total weight (in pounds) of garbage discarded in
one week and the household size were recorded for 62 households. The linear
correlation coefficient is r = 0.759 and the regression equation is.png”>, where x represents the total weight of
discarded garbage. The mean of the 62 garbage weights is 27.4 lb and the 62
households have a mean size of 3.71 people. What is the best predicted number
of people in a household that discards 50 lb of garbage?b. A sample of eight mother daughter
pairs of subjects was obtained, and their heights (in inches) were measured.
The linear correlation coefficient is 0.693 and the regression equation is.png”>, where x represents the height of the mother
(based on data from the National Health Examination Survey). The mean height of
the mothers is 63.1 in. and the mean height of the daughters is 63.3 in. Find
the best predicted height of a daughter given that the mother has a height of
60 in.6. Define
the following terms from section 10-4:a. Total deviationb. Explained deviationc. Unexplained deviation7. Using
the definitions from problem 6, define the following terms and how they relate
to each other:a. Total variationb. Explained variationc. Unexplained variationd. Coefficient of determination8. A wedding caterer
randomly selects clients from the past few years and records the months in
which the wedding receptions were held. The results are listed below (based on
data from The Amazing Almanac).
Assume that you want to test the claim that weddings occur in different months
with the same frequency. Briefly describe what O and E represent, then find the
values of O and E.

9. When using the data
from the above exercise to conduct a hypothesis test of the claim that weddings
occur in the 12 months with equal frequency, we obtain the P-value of 0.477.
What does that P-value tell us about the sample data? What conclusion should be
made?10. The table below
summarizes results from an experiment in which subjects were first classified
as smokers or nonsmokers, then they were given a treatment, then later were
again classified as smokers or nonsmokers.

Before Treatment

Don’t Smoke

After treatment

a. How many subjects are included in the experiment?b. How many subjects changed their smoking status after the treatment?c. How many subjects appear to be unaffected by the treatment one way
or the other?d. Section 9-4 in your textbook presented procedures for data
consisting of matched pairs. Why can’t we use the procedures of Section 9-4 for
the analysis of the results summarized in the table?e. Which of the following pairs of before/after results are discordant?i.
Smoke/Smokeii.
Smoke/Don’t Smokeiii.
Don’t Smoke/Smokeiv.
Don’t Smoke/Don’t Smokef. Using the appropriate frequencies, find the value of the test
statistic.g. Using a 0.01 significance level, find the critical value.h. Based on the preceding results, what do you conclude? How does the
conclusion make sense in terms of the original sample results?PART
II: PROJECTFor
this Module 6 Homework Assignment, please submit your response to the
following:Document your
progress. Who did you interview? How many people did you interview? If you collected data, please submit it
below. If not, please explain what you
did to contribute to this assignment this past week.Directions: This assignment is a course-long project whereby you will work on
the project in each module. You will
turn in your completed project at the end of Module 8.Create a survey question to ask others. The
following are examples or some survey questions:1.
Choose a random number between
1 and 10 inclusive. 2.
What month of the year does
your birthday fall on? Write the numeric
value from 1 to 12.3.
How many keys are in your
possession at this time?4.
How many siblings do you have? In Module 1, you will submit your survey
question to your instructor for approval.
Once you are notified of its approval, you may begin conducting a survey
using your question.You will need at least 25 participants and
will need to keep the following record for each person:a.
Genderb.
Agec.
Date surveyedd.
Survey responsePlease also keep a count, if any, non-willing
participants. For example, if you chose
the first survey question, then you might have the following records:

In the Module 8 Homework Assignment, you will
be asked to analyze your survey results, so please be sure to begin conducting
your survey as soon as your question is approved. Try getting 5 participants a week to satisfy
the required number of participants.
