Forum post (Confidence Interval)
Topic 1: Confidence Interval View Full Description Confidence Intervals for the Mean sigma knownMain PostAssuming .05 as your alpha value, make up a problem similar to this one. Make up 36 gas prices for your example. Use price values in your list that some you made up and be sure they are similar to the prices you have had in your area. List the values in your post.Instructions for your response. You will respond to at least 2 classmates.In your response, describe what you did and give the mean, standard deviation and confidence interval.Example below:
First find the mean. List all 36 gas prices in cells A1 to A36 in your excel spreadsheet.
On a different cell type in =average(A1:A36) and the hit enter to find the average
Assume your answer is 2.65
On a different cell type in =stdev.s(A1:A36) or =stdevA(A1:A36) and enter to find the standard deviation
Assume your answer is .43
Then type this in an excel cell =confidence(.05,.43,36) and hit enter. This is the E value
So take the mean of 2.65 and you have (2.65-E, 2.65+E) for your confidence interval
Formula you used above for the confidence interval:The formula is E= zsubc * sigma / sqrt nWhere the left hand endpoint is xbar - E and the right hand endpoint is xbar + EJust a review of your instructions:
First you will make up a problem with alpha = .05 and give the values for the problem. This is your main post.
Then will make 2 responses explaining all work and giving the solutions to 2 classmates problems.
Instructions: Your initial post should be at least 250 words. Please respond to at least 2 other students. Responses should be a minimum of 100 words and include direct questions.To earn full credit for this forum, you must respond to at least two (2) of your peers and post your initial post by Thurs.

GCCCD Module 22 Stat Crunch Directions and T Score Calculations Problems
Learn by DoingMatched Pairs: In this lab you will learn how to conduct a matched pairs T-test for a population mean using StatCrunch. We will work with a data set that has historical importance in the development of the T-test.Some features of this activity may not work well on a cell phone or tablet. We highly recommend that you complete this activity on a computer.Here are the directions, grading rubric, and definition of high-quality feedback for the Learn by Doing discussion board exercises. A list of StatCrunch directions is provided at the bottom of this page.ContextGosset's Seed Plot DataWilliam S. Gosset was employed by the Guinness brewing company of Dublin. Sample sizes available for experimentation in brewing were necessarily small. At that time, Gosset contacted a famous statistician Karl Pearson (1857-1936) and was told that there were no techniques for developing probability models for small data sets. Gosset studied under Pearson, and the outcome of his study was perhaps the most famous paper in statistical literature, "The Probable Error of a Mean" (1908), which introduced the T-distribution.Since Gosset was employed by Guinness, any work he produced would be owned by Guinness, so he published under a pseudonym, "Student"; hence, the T-distribution is often referred to as Student's T-distribution.To illustrate his analysis, Gosset used the results of seeding 11 different plots of land with two different types of seed: regular and kiln-dried. He wanted to determine if drying seeds before planting increased plant yield. Since different plots of soil may be naturally more fertile, this confounding variable was eliminated by using the matched pairs design and planting both types of seed in all 11 plots.The resulting data (corn yield in pounds per acre) are as follows.PlotRegular seedKiln-dried Seed11903200921935191531910201142496246352108218061961192572060212281444148291612154210131614431115111535We use these data to test the hypothesis that kiln-dried seed yields more corn than regular seed.Because of the nature of the experimental design (matched pairs), we are testing the difference in yield.PlotRegular seedKiln-dried SeedDifference119032009–10621935191520319102011–10142496246333521082180–7261961192536720602122–62814441482–38916121542701013161443–1271115111535–24Note that the differences were calculated: regular − kiln-dried.VariablesRegular seed: regular seeds that were traditionally used for plantingkiln-dried: seed that were kiln-dried before plantingDataDownload the seed (Links to an external site.) data file, and then upload the file into StatCrunch.

WU Quantitative Reasoning & Analysis Multiple Regression in Practice Discussion
For this Assignment, you will continue your practice as a critical consumer of research. You will critically evaluate a scholarly article related to multiple regression. Search for a quantitative article that includes multiple regression testing.Write a 3- to 5-paragraphs critique of the article (2 to 3 pages). In your critique, include responses to the following:
Why did the authors use multiple regression?
Do you think it’s the most appropriate choice? Why or why not?
Did the authors display the data?
Do the results stand alone? Why or why not?
Did the authors report effect size? If yes, is this meaningful?
Use proper APA format, citations, and referencing.Required Readings

Understanding the probability key, statistics homework help
You are a marketing manager for a manufacturer of nonperishable products sold in grocery stores. In this role, you need to make various decisions about how much marketing/advertising support is needed by each product to maximize the profitability of the organization.Assess how the effectiveness of individual marketing/advertising approaches would be determined.Discuss how historical sales data, as well as promotional response data, can aid you in evaluating the effectiveness of the individual marketing/advertising approaches. Support your discussion with relevant examples, research, and rationale.The final paragraph (three or four sentences) of your initial post should summarize the one or two key points that you are making in your initial response.
