a.
Does this table describe a
relative frequency distribution? Why or why not? b.
What are some of the conditions
for a table to have a relative frequency distribution? 2. Listed below are
amounts of strontium-90 (in millibecquerels) in a simple random sample of baby
teeth obtained from Pennsylvania residents born after 1979 (based on data from
“An Unexpected Rise in Strontium-90 in U.S. Deciduous Teeth in the 1990s,” by Mangano,
et. al., Science of the Total Environment). Construct a frequency distribution
with eight classes. Begin with a lower class limit of 110, and use a class
width of 10. Cite a reason why such data are important. You may use the blank
table below or create your own.155 142 149 130 151 163 151 142 156 133 138

about the distribution of those amounts? You may use the table below to create

Construct a cumulative frequency distribution
given the frequency distribution table above.6. Assume that, as a
newspaper reporter, you must graph data showing that increased smoking causes
an increased risk of lung cancer. Given
that people might be helped and lives might be saved by creating a graph that
exaggerates the risk of lung cancer, is it ethical to construct such a graph?7. In an editorial, the Poughkeepsie
Journal printed this statement: “The median price–the price exactly
in between the highest and lowest–…”
Does that statement correctly describe the median? Why or why not?8. When the Indianapolis
Colts recently won the Super Bowl, the numbers on the jerseys of the active
players were 29, 41, 50, 58, 79,…, 10 (listed in the alphabetical order of
the player’s names). Does it make sense
to calculate the mean of those numbers?
Why or why not?9. In statistics, how do variation
and variance differ?10. Which do you think has
more variation: the incomes of a simple random sample of 1000 adults selected
from the general population, or the incomes of a simple random sample of 1000
statistics teachers? Explain.11. Listed below are the
annual salaries for a simple random sample of NCAA football coaches (based on
data from USA Today). How does the standard deviation change if the highest
salary is omitted? Compute the standard deviation of the entire list first then
compute the standard deviation while omitting the highest salary.$150,000 $300,000 $350,147
$232,425 $360,000 $1,231,421 $810,000 $229,00012. Dr. Smith’s Generac
generator produces voltage amounts with a mean of 125.0 volts and a standard
deviation of 0.3 volt. a.
Using Chebyshev’s theorem, what
do we know about the percentage of voltage amounts that are within 3 standard
deviations of the mean? b.
What are the minimum and
maximum voltage amounts that are within 3 standard deviations of the mean?13. Bao Xishun is the
world’s tallest man with a height of 92.95 in. (or 7 ft, 8.95 in.). Men have
heights with a mean of 69.6 in. and a standard deviation of 2.8 in.a.
What is the difference between
Bao’s height and the mean height of men?b.
How many standard deviations is
that (the difference found in part (a))?c.
Convert Bao’s height to a
zscore.d.
Does Bao’s height meet the
criterion of being unusual by corresponding to a z score that does not fall
between and 2?14. A physician routinely
makes physical examinations of children. She is concerned that a three-year-old
girl has a height of only 87.8 cm. Heights of three-year-old girls have a mean
of 97.5 cm and a standard deviation of 6.9 cm (based on data from the National
Health and Nutrition Examination Survey). a.
Use the range rule of thumb to
find the maximum and minimum usual heights of three-year-old girls. b.
Based on the result, is the
height of 87.8 cm unusual? c.
Should the physician be
concerned?15. Use the given sorted
values below which are the numbers of points scored in the Super Bowl for a
recent period of 24 years.36 37

II: PROJECTFor
this Module 2 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.
