Explanation & Answer
x1-x2=16. We need a pooled standard deviation. This is sqrt(s1^2/n1+s2^2/n2) That is, sqrt(16^2/6+34^2/11) . This yields 12.156 . The z score for 90% confidence is 1.645. Thus we have 16+/-12.156*1.645= (-4,36).

University of Phoenix Data Analysis and Random Variables Discussion Post
Respond to the following discussion prompt in a minimum of 175 - 500 words:Many business activities generate data that can be thought of as random. An example described in the textbook is the servicing of cars at an oil change shop. Each car entering the shop can be considered an experiment with random outcomes. A variable of interest in this experiment could be the amount of time necessary to service the car. Service time will vary randomly with each car.We can often capture the most relevant characteristics of a stochastic process with a simple probability distribution model. We can then analyze the model to make predictions and drive decisions. For instance, we could estimate the number of technicians the oil change shop needs to service demand on a Saturday afternoon. Discuss the following:What is a random variable?How would you differentiate a discrete from a continuous random variable?A laptop manufacturing company has implemented a 2-step process to test the quality of each production batch. In the first step, a technician randomly selects 15 laptops from the batch and determines whether they meet specifications. The batch is considered acceptable provided no more than 1 laptop fails to meet specifications. Otherwise, the entire batch must be tested in the second step. Historical data shows that 95% of the laptops produced adhere to specifications. Discuss the following:What are the 4 characteristics of a binomial experiment?Can we use a binomial distribution to model this process?What is the probability that the entire batch unnecessarily has to be tested if in fact 95% of its laptops conform to specifications? (Hint: Use Excel’s =BINOMDIST() function to find the probability.)What is the probability that the batch is incorrectly accepted if only 75% of its laptops conform to specifications?

Program Student Learning Outcomes are broad statements that describe what students should know and be able to do upon completion of their degree. The signature assignment may be graded with an automated rubric that allows the University to collect data that can be aggregated across a location or college/school and used for program improvements. Purpose of Assignment The purpose of this assignment is for students to synthesize the concepts learned throughout the course, provide students an opportunity to build critical thinking skills, develop businesses and organizations, and solve problems that require data. Assignment Steps Case 1: Scenario: Cloud Data Services (CDS), headquartered in Memphis, provides information technology services, specifically application hosting services in the cloud for several clients in the southern United States. CDS hosts software applications on their network servers. While CDS has achieved great success and customers rate CDS's services highly, lately, some customers have been complaining about downtime on one of the primary network servers. The given dataset, found in the Signature Assignment Excel® Template, contains the downtime data for the month of November.Use the data analytics skills learned in Week 3 and analyze the downtime data.Make a short presentation to CDS's management including the following:1.Using used Microsoft® Excel® Pivot Tables, construct a frequency distribution showing the number of times during the month that the server was down for each downtime cause category.2.Develop a bar chart that displays the data from the frequency distribution in part 1.3.Develop a pie chart that breaks down the percentage of total downtime that is attributed to each downtime cause during the month.4.Evaluate the mean, median, standard deviation, and variance of the downtime minutes for the month of November.Case 2:Note: Although you will be studying the concept of CPI in more detail in your ECO/561 class; for the purpose of this case, you need to use the concepts of percentages, percentage increase/decrease, and creating and interpreting line charts to compute the inflation rate in the US economy and determine which time period experienced the highest inflation rate. Follow the steps below to complete this signature assignment: 1.Search for the Federal Reserve Bank of St. Louis (FRED).2.On the home page of the website, you will see a search box.3.Type in CPI- AUCSL in the search box and press the return key.4.The first result of the search will be "Consumer Price Index for All Urban Consumers: All Items." Click on this result link.5.Click on the Download link and download the data in Excel®.6.On the Excel® file, the second column gives you the CPI values for each period starting from 1947.7.Go to the last row and notice the last date and the CPI value. Go back 6 years from this last date. For example, if the last date is 2016-11-01, then the date 6 years ago would be 2010-11-01.8.Copy and paste this six years data into a separate Excel® tab.9.Using Excel®, calculate the percentage change in CPI from a year earlier for each observation, beginning with the observation one year later than the first observation. To make this calculation, click on the blank cell next to the observation corresponding to that date and then use Formula 1, located in the Signature Assignment Excel® Formulas document (note that in Excel®, the symbol for multiplication is *), where t-1 is the first observation and t is the observation one year later. For example, to find the percentage change in CPI from 2010-11-01 to 2010-10-01, refer to Formula 2 located in the Signature Assignment Excel® Formulas document. Convert this value to a percentage in Excel®. Repeat this process for the remaining observations (you can use the copy and paste functions to avoid having to retype the formula).10.This new column contains the national inflation rate.11.Create a line graph of the percentage changes (inflation rates) from a year earlier.12.Which period experienced the highest inflation rate? What was the inflation rate during that period?Format your assignment consistent with APA guidelines. Click the Assignment Files tab to submit your assignment.

Week 6 DQ 1, statistics homework help
Consider the following news headline, "Cigarette Smokers Make Lower College Grades Than Nonsmokers." The article goes on to say that researchers at a university collected information on the rate of cigarette smoking (total number of cigarettes smoked in a one-month period) and the college student's current GPA for completed college courses. They found that those with higher levels of cigarette use had lower GPAs, and vice versa. What can you rightfully conclude from this? Why? Be specific about what this kind of information may indicate and mean.Please respond to the above question using 250 words. Please also use at least 1 reference that is from a peer reviewed article or journal not a website reference. Please also cite the reference in APA 6th edition format.
