George Mason University Module 8 Tree Diagram & Law of Total Probability HW
From your own experiences, create a scenario that will require the use of a tree diagram to determine probability of related events. Be sure that your scenario has at least two related events. (You may use the examples from section 8.7 of your text as a guide.) Create at least four questions based on your scenario:Create a Tree Diagram to model the scenarioQuestion that requires application of Conditional ProbabilityQuestion that requires the Law of Total ProbabilityQuestion that implements Bayes' Theorem via Conditional ProbabilityQuestion 1Create a scenario from your own experiences that can be used to model a probability problem with related events, where there is dependency presented between the events (see your text, section 8.7 for guidance.)Question 2Draw a Tree Diagram to show the relationship between all of your presented events. Label each part of the tree using the identified events and the corresponding probabilities.Question 3Create a question that requires Conditional Probability based on the information in your tree.Provide a response to that question, you must phrase your response in terms of the events identified on your tree.Question 4Provide a question that requires the Law of Total Probability.Provide an answer to the question that applies the Law of Total Probability. Be sure to phrase in terms of events.Question 5Provide a question that requires use of information on your tree in application of Bayes' Theorem.Provide a solution to your question, be sure to phrase in terms of the events provided on your tree and show each step

Grossmont College Hypothesis Test for A Population Mean Lab Questions
Context
A group of 75 college students from a liberal arts college were randomly sampled and asked about the number of alcoholic drinks they have in a typical week. The file containing the data is linked below. The purpose of this study (Links to an external site.) was to compare the drinking habits of the students at the college to the drinking habits of college students in general. In particular, the dean of students, who initiated this study, would like to check whether the mean number of alcoholic drinks that students at his college have in a typical week differs from the mean of U.S. college students in general, which is estimated to be 4.73.
Variables
The number of alcoholic beverages a student consumes in a week.
Data
Download the drinks (Links to an external site.) data file and then upload the datafile in StatCrunch.
Prompt
The drinks datafile is available in the Data section below.
Let ?? be the mean number of alcoholic beverages that students in the liberal arts college drink in a typical week. State the hypotheses.
Here is a histogram of the data. Can we safely use the t-test with this data? Explain.
Perform the t-test using StatCrunch. (directions)
Copy and paste the information from the StatCrunch output window into your initial post.
Based on the P-value, state your conclusions in context. Use a 5% level of significance.
NOTE: You do not need to double the P-value for this two-tailed test. StatCrunch calculates the P-value for you.
Using the context of this scenario, explain the meaning of each of following items from the StatCrunch output for the hypothesis test.
Std. Err (standard error)
T-stat (T-score)
P-value

Statistics module 2 discussion homework help
Please make this as short as possible, it's only a discussion post. Assume that you are interested in doing a statistical survey and using confidence intervals for your conclusion. Describe a possible scenario and indicate what the population is, and what measure of the population you would try to estimate (proportion or mean) by using a sample.What is your estimate of the population size?What sample size will you use? Why?How will you gather information for your sample? Describe your process.What confidence percentage will you use? Why?

Assignment 1: Binary Logistic Regression in SPSS
Please use the following data set (attached) and template (listed below and attached) to conduct the following assignment,In this Assignment, you apply what you learned to answer a social research question using logistic regression.To prepareReview the datasets provided.Construct a research question based on one of those datasets.Remember that your dependent variable must be dichotomous.Think about how you might use the odds ratio in your analysis to simplify the interpretation of your results.The AssignmentUse SPSS to answer the research question you constructed. Then, compose a 1- to 2-paragraph analysis in APA format in which you answer the following questions:What is the null hypothesis for your question?What research design(s) would align with this question?What dependent variable was used and how is it measured?What independent variable is used and how is it measured?How well did the model fit?If you found significance, what is the strength of the effect?What is the answer to your research question?What are the possible implications of social change?Be sure to include your data output with your analysis. See page 1032 in your Warner textbook for an excellent APA-compliant write-up of a binary logistic regression analysis.
