Linear Regressions
Choose any Excel Discussion dataset. Include the name of the dataset. From that dataset, select any two quantitative variables that you suspect will be related (such as age and height for example). What is the name of the dataset you have chosen? Which two variables did you choose?Next, using Excel, calculate the relationship (r value) between the two variables. Recall that the Excel “formula” for correlation is “=CORREL.” What is the r value for the two variables that you have chosen? Is it positive or negative? Is it strong, medium, or weak? Note that it is best to have an r value that is medium or strong. It is recommended that you try a few different variables until you find two variables with an r value between .5 and 1 (or between -.5 and -1).Next, use Excel to create a scatterplot for the two variables. You decide which variable will be dependent (y) and which will be independent (x). On the scatterplot, include the “trendline” and the “equation for the line” using Excel options. Attach your scatterplot to your post.Finally, using the equation of the line that you generated above, plug in any reasonable value for x (your chosen independent variable) and solve the equation for y (your chosen dependent variable). It is up to you to determine which of your two variables is x and which is y. What prediction do you get? Show all your work. In other words, type out the equation, plug in a value for x, and show your solution for y.

Airshow Day Mean and Standard Deviation Report
Part1:IntroductionThis discussion provides a simulated exercise using two of the most popular descriptive statistics, mean and standard deviation. You are strongly encouraged to complete the textbook reading and start the MyStatLab Homework assignment before beginning this discussion. You need to be familiar with mean and standard deviation, their interpretation, and why they are typically calculated and reported together.In this discussion, you are required to calculate and interpret the reported mean and standard deviation values. In the Module 2 - Assignment: Airshow Day 1: Winner, you will be required to concisely report (interpret) results obtained in this discussion. ScenarioCongratulations on your promotion! You are now leading the team. After one week in your new position, your supervisor provides guidance for your new assignment, responsibility for an important and “very visible” task.In one month, your airport is hosting an airshow that allows potential future customers to observe the flying capabilities of civilian and military aircraft. Support teams are planning for over 100,000 to attend the two-day event. Your tasks are to determine and officially report the “Winner;” a very prestigious honor; highly valued in both civilian and military communities.Fortunately, your predecessor (an Embry-Riddle graduate) has provided a Microsoft Excel template:Module 2 Airshow Discussion Excel Template-1.xlsxDay one arrives, the weather is almost perfect, clear skies, 70o F with intermittent moderate to strong runway crosswinds (20 Knots sustained, gusts to 33 Knots). Fortunately, all flying sorties are accomplished without incident.Data were collected on each aircraft for each sortie. A mean or sample standard deviation value of zero (0) is the lowest possible score. Reported data are unitless. Higher overall aircraft mean scores are better; lower aircraft sample standard deviations are also better.Data your team collected are reported in the Airshow - US Military Aircraft Performance chart.Using Microsoft Excel, complete the "Airshow – US Military Aircraft Performance" table by calculating column and row values for mean and sample standard deviation; report your values to two decimal places (i.e., 0.12). Remember, the focus of this discussion is understanding and interpreting two descriptive statistics, mean and standard deviation.Insure only objective (data-based!) discussions.Save your work as a file to your computer and then read the Canvas instructions on How do I embed an image in a discussion reply as a student? (Links to an external site.)Post & DiscussPost the image of your spreadsheet into the discussion area along with a narrative (interpretation!) of your findings before the fourth day of the module week to receive full credit. Address the following questions in your narrative.Is there a difference between the type of aircraft (i.e., Tankers, Transports, Bombers, and Fighters)?What do the differences (if any) appear to indicate?Return at least twice later in the module week to provide meaningful (substantive) comments to two or more of your classmates' posts. DO NOT “post and run” – making all three posts in the same visit. You need multiple visits to the discussion area to gain multiple perspectives by reading all of the posts and replies.Review the Discussion Rubric for detailed grading information.Part2:IntroductionThis writing assignment provides you with practical experience in reporting calculated data using a Memorandum of Understanding (MOU). MOUs are common, both domestically and abroad. They vary in length and complexity, but each MOU represents mutually accepted expectations between people, organizations or governments.An MOU should:Clearly outline specific points of understanding.Describe who the parties are and the project for which they are agreeing.ScenarioDuring Day 1 of the Airshow, an emergency required the launch of an additional sortie for the KC-135. Because members of your team were already on board, they recorded an additional aircraft data point of 10.71. Use the spreadsheet that you created for the Module 2 - Discussion: Airshow Day 1: Mean and Standard Deviation to:Calculate the new KC-135 Mean and Standard Deviation for eleven sorties.Determine the impact (if any) Sortie 11 has on the original ten KC-135 sortie mean and standard deviation calculated values.Report the WinnerNow that you have all of the data, report the Day 1 Winner and the KC 135 Sortie 11 results. The winner is the aircraft type scoring 1) the highest mean and then 2) the lowest standard deviation (in the event of a tie). Report the winner and the KC 135 Sortie 11 results in a Memorandum of Understanding document. Your document should be a maximum of one page with one-inch margins using 11 point font and consist of only the following three paragraphs:Introduction - Prepare the audience for what he/she is about to read.Results - The facts.Conclusion(s) - Results are fact(s) based, concise and to the point; actionable.Review the Writing Suggestions page for tips.

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?
