Week 5 discussion board : Polling Organizations: Polling agencies claim to provide accurate
readings of the pulse of America. They give the public a percentage of the population who are likely to
vote for a particular candidate, or a company the probability that their customers may purchase their
product. Polling organizations sample the population and use a proportion to predict the results during an
election or the likelihood a customer will buy. Choose a polling organization and look up a current
sampling situation. Discuss the poll, sample size, point-estimate, margin of error, and inferences. Explain
the importance of this data and what you find interesting about the results. Be sure to provide a reference
to your poll!
Week 6 discussion board : Google Scholar or Chapman/Brandman Library Research: Use
Google Scholar or the Library tab on Blackboard to find a research study in any area of interest to you
that involves hypothesis testing. Describe the study, hypothesis test, null/alternative hypothesis, alpha
value, one or two-tailed test, results, and inferences made. Please make sure you cite references to any
sources you use for this question. Provide a link to the actual study so that classmates can review the
hypothesis test data. Explain the inferences you make from these results, importance of this data in
general, how it relates to your life, and what you find interesting about the study.
Week 6 technology assignment : Download the data set “Airport Speeds” in your preferred
technology format (StatCrunch, Statdisk, Excel). Column 2 denotes the data speeds (Mbps),
taken from 50 different airports, for the carrier Verizon. Column 4 denotes the data speeds
(Mbps) for the carrier AT&T from the same 50 airports.
Using technology (StatCrunch, Statdisk, or Excel) compute the mean data speed for
each of the two carriers, Verizon and AT&T. Provide a printout of your technology output using
the Insert/Edit Image feature (no attachments!) Based on this, which carrier do you think has
the faster speed?
Next, using technology (StatCrunch, Statdisk, or Excel) conduct a hypothesis test to test
your claim about which carrier has the faster speed. Explain which test you conducted
and why that is the appropriate test for this example. Provide a printout of your technology
output using the Insert/Edit Image feature (no attachments!) Explain your conclusion in statistical
and non-statistical terms and how you arrived at that conclusion. Be sure to follow the
8-step procedure on page 360, using technology to do your calculations. You should
include your null and alternative hypothesis (in English and in symbolic form), your
significance level, whether you are conducting a right tailed, left tailed, or two tailed test,
p-value, and conclusions.
Week 7 discussion board : Correlation – There was a not a placement test for this class, but do
you think there would be a positive correlation between a placement test score and the final grade in this
class? What other variables do you think would have a positive correlation with the final grade in this (or
any) class? What variables would have a negative correlation with a final grade in a class? Look up a
study that finds a correlation between grades and some other variables. Describe the variables, the
study, the methods used, whether the correlation is positive or negative, and how this relates to your
life. Be sure to provide a reference!
Week 7 technology assignment : Download
the data set “Course Evaluations” in your
preferred technology format (StatCrunch, Statdisk, Excel). Column 2 denotes the mean
course rating, and Column 3 denotes the mean professor rating. Using your preferred
technology format (StatCrunch, Statdisk, Excel), generate a scatterplot for these two
data sets. Based on the graph, do you believe the two sets are correlated?
Now, using the same program, complete a hypothesis test to test the claim that the
course rating and the professor rating are correlated. Provide a printout of your technology
output using the Insert/Edit Image feature (no attachments!) Explain your conclusion in
statistical and non-statistical terms and how you arrived at that conclusion. Be sure to
follow the 8-step procedure on page 360, using technology to do your calculations. You
should include your null and alternative hypothesis (in English and in symbolic form),
your significance level, whether you are conducting a right tailed, left tailed, or two tailed
test, r-value, p-value, and conclusions.
