Discussion: Probability in Real Life

People use probability to make many decisions. We must remember, however, that statistical probability deals only with random events, or things that happen by chance. For example, flipping a fair coin is a random event because each side has an equal likelihood of landing facing up. When faced with making a conscious choice based on probability, decisions often become more complex because they are not random.  Consider the example of deciding whether to buy a lottery ticket. You have two choices: buy a ticket or do not buy a ticket. The probability of each decision is not .50 (fifty-fifty), however, as you might expect, because many factors help you make that measured decision; your choice is not random. The cost of the ticket, the amount of the jackpot, your feelings about gambling, and even your mood at the moment weigh into your decision.  In contrast, the probability of you winning the jackpot if you do deci

Develop a 700- to 1,050-word statistical analysis based on the Case Study Scenarios and SpeedX Payment Times. 

Include answers to the following: 

Case 1: Election Results 

  • Use 0.10 as the significance level ().
  • Conduct a one-sample hypothesis test to determine if the networks should announce at 8:01 P.M. the Republican candidate George W. Bush will win the state. 
  • Case 2: SpeedX
  • Use 0.10 and the significance level ().
  • Conduct a one-sample hypothesis test and determine if you can convince the CFO to conclude the plan will be profitable.

Assignment Content

  1. Purpose of Assignment 
    The purpose of this assignment is to develop students' abilities to combine the knowledge of descriptive statistics covered in Weeks 1 and 2 and one-sample hypothesis testing to make managerial decisions. In this assignment, students will learn how statistical analysis is used in predicting an election winner in the first case. In the second case, students will conduct a hypothesis test to decide whether or not a shipping plan will be profitable.

Provide a 1,600-word detailed, four part, statistical report with the following sections:

  • Part 1 - Preliminary Analysis
  • Part 2 - Examination of Descriptive Statistics
  • Part 3 - Examination of Inferential Statistics
  • Part 4 - Conclusion/Recommendations 

Part 1 - Preliminary Analysis

Generally, as a statistics consultant, you will be given a problem and data. At times, you may have to gather additional data. For this assignment, assume all the data is already gathered for you.

State the objective:

  • What are the questions you are trying to address?

Describe the population in the study clearly and in sufficient detail:

  • What is the sample?

Discuss the types of data and variables:

  • Are the data quantitative or qualitative?

Exploring Global Student Values With Descriptive Statistics

PROJECT 2: Exploring Global Student Values with Descriptive Statistics

For this project, we are exploring the global social values of our classmates. You will be asked to analyze three (3) different variables taken from Pew Research Centers survey on Global Attitudes and Trends (GAT) For each variable, you will need to compose a detailed statistical report, a frequency distribution (lesson 2), a graph/chart (lesson 2), a central tendency analysis (lesson 3), and a variability analysis (lesson 4). This project emphasizes learning goals and objectives 1, 2, 3, and 7 as listed in the syllabus.

Graphing And Describing Data In Everyday Life


Suppose that you have two sets of data to work with. The first set is a list of all the injuries that were seen in a clinic in a month's time. The second set contains data on the number of minutes that each patient spent in the waiting room of a doctor's office. You can make assumptions about other information or variables that are included in each data set.

For each data set, propose your idea of how best to represent the key information. To organize your data would you choose to use a frequency table, a cumulative frequency table, or a relative frequency table? Why?

What type of graph would you use to display the organized data from each frequency distribution? What would be shown on each of the axes for each graph?
