I will provide you witht he data set and you have to download SPSS if you do not already have it. I will also send assignment with rubric so you know how it is graded. We have to provide sufficient answers to support our knowledge. the book for the class is Behavioral Sciences STAT - With Access 2ND 15Author: Heiman, GaryISBN-13: 978-1-285-45814-4ISBN-10: 1-285-45814-1Edition/Copyright: 2ND 15Publisher: Wadsworth, Incwill copy and paste assignment below:Scenario: Imagine you are a researcher who is interested in studying whether sleep deprivation leads to increased reaction times (i.e., being slower) when driving. You randomly select a sample of 30 licensed drivers. Fifteen participants are randomly assigned to get 5 hours of sleep for three consecutive nights. The other 15 participants are randomly assigned to get 8 hours of sleep for three consecutive nights. For the purposes of this Assignment, assume that all participants sleep exactly the required amounts. After the third night, all participants take a driving simulation test that measures their reaction times.You can find the data for this Assignment in the Weekly Data Set forum. By Day 7To complete this Assignment, submit a response to each of the following. Use SPSS to determine if amount of sleep is related to reaction time.Explain whether the researcher should use an independent-samples t-test or a related-samples t-test for this scenario. Provide a rationale for your decision.Identify the independent variable and dependent variable.Knowing the researcher believes that people who sleep less will have slower reaction times, state the null hypothesis and alternate hypothesis in words (not formulas).Explain whether the researcher should use a one-tailed test or two-tailed test and why.Identify the obtained t value for this data set using SPSS and report it in your answer document.State the degrees of freedom and explain how you calculated it by hand.Identify the p value using SPSS and report it in your answer document.Explain whether the researcher should retain or reject the null hypothesis. Provide a rationale for your decision. Are the results statistically significant?Explain what the researcher can conclude about the relationship between amount of sleep and reaction times.Be sure to fully explain the rationale for your answer to each question, including evidence from the text and Learning Resources.Provide an APA reference list.Submit three documents for grading:Your text (Word) document with your answers and explanations to the assignment questions, your SPSS Data file, and your SPSS Output file.DATA SET BELOW:

business statistics - critical thinking question finding descriptive statistics and making report
Finer Suit Company sells suits in the US and the European Union. The
company monitors its suit sales by collecting randomly chosen data from
store locations throughout the US and the EU. They record list price (in
dollars), sale price (in dollars), and number of days it takes to sell
each suit. Data were collected from 200 suits sold in the US and 200 in
the EU region. The complete data set is in the file named Suits.Managerial ReportPrepare a report (see below) that summarizes your assessment of the
nature of the suit market in each region. Be sure to include the
following seven items in your report.Calculate descriptive statistics (mean, median, range, standard
deviation, and coefficient of variation) to summarize each of the three
variables for the all US suits. Use z-scores to determine if there any
outliers in the data set for any of the three variables.
If there are any outliers in any category, please list them and state for which category they are an outlier.If a result is an outlier, state whether it is below or above the mean.How can one use the above descriptive statistics to understand the
US suit market better? Could there be any other descriptive statistics
that can help one understand the US suit market better?

Assume the Finer Suit Company requested estimates of the mean List
Price for the US suits with a margin of error of $600 and the mean List
Price of EU suits with a margin of error of $600. Using 99% confidence,
how large should the sample sizes be for each one?
How could the sample size formula be useful in understanding both
types of suit businesses? What are some advantages of a larger sample
size?
Suppose a US suit has a list price of $1,500 and an EU suit has a
list price of $1,200. What is your estimate of the final selling price
(based on the percent difference for the sale and list price) and number
of days required to sell each of these suits?
How would these two estimates be useful in this application?

the problem, and, for each question, show all steps involved. Be sure
this is in paragraph format, not numbered answers like a homework
assignment.The conclusion should summarize your thoughts about what you have
determined from the data and your analysis, often with a broader
personal or societal perspective in mind. Nothing new should be
introduced in the conclusion that was not previously discussed in the
body paragraphs.Include any tables of data or calculations, calculated values,
and/or graphs associated with this problem in the body of your
assignment.
