Description
The current i amperes flowing in a
capacitor at time t seconds is given by
i =8.0(1−e−t CR ), where the circuit resistance R is
25×103 ohms and capacitance C is
16×10−6 farads. Determine (a) the current i after
0.5seconds and (b) the time, to the nearest
millisecond, for the current to reach 6.0A. Sketch
the graph of current against time.

BUS 320 Westcliff University Pace of Life Preferences by Gender Statistics Questions
Pace-of-Life Preference by Gender. A Pew Research Center survey asked respondents if they would rather live in a place with a slower pace of life or a place with a faster pace of life. The survey also asked the respondent’s gender. Consider the following sample data.a. Is the preferred pace of life independent of gender? Using a .05 level of significance, what is the p-value, and what is your conclusion?b. Discuss any differences between the preferences of men and women.

Ashford University Sampling Methods Relating to Statistics Discussion Post
THIS IS A DISCUSSION POST ONLY!150 to 250 WordsThis video discusses sampling in the context of how estimates of population parameters are obtained. It refers to Video 1: What is an Average? where we obtained an “average of 1.89 feet per person.” It points out that applying this statistic depends on thinking through whom the population is meant to be, and that depends on the study question (i.e., “If you want to understand your answer, you really have to work out carefully what your question is.”).As the sample statistic was derived from a bunch of kids heading to the playground, plus a one-legged man who we asked to show up, we conclude that the sample was a bad one. We explain that random sampling is generally a good way of obtaining a representative sample such that you can be confident that the sample statistic is a good estimate of the population parameter.Respond to the following response below:Magazines often report surveys giving statistics such as “63% of women expect the man to pay on the first date.” Are these random samples? These surveys are most definitely not random – they are typically click-through from the magazine website – and so can provide an opportunity to discuss the sort of biases that can result from lack of random sampling.Video 3 Below:https://mediaplayer.pearsoncmg.com/assets/MsQQxcXFvHB_VZh1oA5V861T4AL2Cenj

Walden University Testing for Correlation and Bivariate Regression Paper
Assignment: Testing for Correlation and Bivariate Regression You had the chance earlier in the week to perform an article critique on correlation and simple linear regression and obtain peer feedback. Hopefully you are excited about the potential these tests hold; equally important is that you recognize some of their weaknesses. Now, it is once again time to put all of that good brainstorming to use and answer a social research question with the correlation and simple linear regression. As you begin the Assignment, be sure and pay close attention to the assumptions of the test. Specifically, make sure that your variables are metric level variables that can easily be interpreted in these tests. For this Assignment, you will examine correlation and bivariate regression testing. To prepare for this Assignment: Review this week’s Learning Resources and media program related to regression and correlation.Using the SPSS software, open the Afrobarometer dataset or the High School Longitudinal Study dataset (whichever you choose) found in the Learning Resources for this week.Based on the dataset you chose, construct a research question that can be answered with a Pearson correlation and bivariate regression.Once you perform your correlation and bivariate regression analysis, review Chapter 11 of the Wagner text to understand how to copy and paste your output into your Word document. For this Assignment: Write a 2- to 3-paragraph analysis of your correlation and bivariate regression results for each research question. Do not forget to evaluate if the correlation and bivariate regression assumptions are met and report the effect size. In your analysis, display the data for the output. Based on your results, provide an explanation of what the implications of social change might be.Refernces Laureate Education (Producer). (2016b). Correlation and bivariate regression [Video file].

FPX 5008 Capella Interpreting Graphical Representations of Data Walmart PPT
You have been invited to be one of many presenters at a departmental
meeting that employees of all levels will attend. You have been allotted
5–8 minutes, and the purpose of your speech is to explain the two
charts or tables that your analyst has given you.Instructions
Select two graphical representations of data, such as pie charts, bar charts, scatter plots and trend lines, or tables.
You may use published articles, annual report graphics from publicly traded companies, or any published business report.
You may find your own article that meets the criteria.
Identify the business context, such as an online store, a
brick-and-mortar business, year-end review, product kickoff, recently
merged or new IPO company, or a family-owned business.
This company background information should help explain why the data is relevant.
Interpret your chosen data representation in the context of the
business situation. The following are typical questions an analyst would
use to interpret the data:
What is being measured (the variables)?
What are the relationships among the variables?
What are the trends in the data?
How can the data be applied in the business context?
Create an effective 6-slide PowerPoint presentation that could be presented at a departmental meeting.
An effective PowerPoint presentation for this purpose typically includes:
1 title slide, APA formatted.
1 introduction slide explaining the business context.
1 slide for each of the two graphics in your report.
You may insert or paste the charts and include an appropriate citation (2 total slides for this portion of the presentation).
Explain the meaning of each graphical data representation.
1 conclusion slide in which you explain how the data may
affect the business context or how each graph may be applied in your
business context to inform decision making.
1 slide with APA-formatted references, including the source of each graph.
Prepare a short speech that presents your analysis so that it is relevant to people of all levels of the company.
