confidence intervals and Minitab output In order to understand how hypothesis testing is done it is important that you know the elements of the Test of Hypothesis‚ and what each step means. The Seven elements of a Test of Hypothesis are: 1. Null Hypothesis - A theory about the specific values of one or more population parameters. The theory generally represents the status quo‚ and we accept it until proven false. 2. Alternative (research) hypothesis (Ha)- A theory about the specific

Summary: AJ Davis department store has asked to take a look at a sample of customers (sample size: 50) in order to more efficiently generate sales and also appeal to their more profitable segment. In order to better understand their customers a statistical analysis and interpretation must be performed. AJ Davis is hoping to achieve insight on how to improve their department store operations and strengthen their customer loyalty. We have taken both quantifiable and qualitative information and

PROJECT PART C: Regression and Correlation Analysis Math-533 Applied Managerial Statistics Prof. Jeffrey Frakes December 12‚ 2014 Jared D Stock 1. Generate a scatterplot for income ($1‚000) versus credit balance ($)‚ including the graph of the best fit line. Interpret. This scatter plot graph is a representation of combining income and credit balance. It shows the income increasing as the credit balance increases. As a result of this data it can be inferred that there is

Course Project Part Three Professor Douglas Nottingham March 27‚ 2014 1. Generate a scatterplot for CREDIT BALANCE vs. SIZE‚ including the graph of the "best fit" line. Interpret. The larger the size of the family the larger the credit balances is for the family. The larger families have the financial needs to have a larger credit balance. 2. Determine the equation of the "best fit" line‚ which describes the relationship between CREDIT BALANCE and SIZE. Credit Balance ($)
