1. Scatterplot for Credit Balance vs Size Analyzing the scatterplot credit balance vs size, it seems like size (x) will be a good predictor of credit balance (y). The line has a positive slope, and shows that when x increase per 1 unit, y will change by the slope. 2. Equation that describes the relationship between Credit Balance vs Size Y = β0 + β1 β0 : y – intercept β1 : slope Credit Balance($) = 2591.44 + 403.221 Size 3. Coefficient of correlation R = √R2 R = √ 0.5662 = 0.75246262 When we have a high coefficient of correlation like 0.75, means that there is a strong linear relationship between the credit balance and the size. 4. Coefficient of determination R2 = 0.5662 = 56.62 % The …show more content…
Reject H0 X1 (Income): T- Value = 7.42196 is greater than F0.025 = 2. Reject H0 X2 (size): T- Value = 9.62668 is greater than F0.025 = 2. Reject H0 X3 (years): T- Value = 0.63885 is less than F0.025 = 2. Do not reject H0 We have strong evidence that X1 and X2 are significantly related to Y. However, there is insufficient evidence that X3 is related to Y. Therefore, we should keep X1 and X2, but discard X3. 14. Is the Multiple Regression model better than the Linear model? All the results show the relationship between income and size with credit balance, which have sense because with high income and larger household you have more expenses, which translate in more credit balance. Nevertheless, how many years you live in an area don’t necessarily mean more credit balance. This support that Multiple Linear Regression model is better than the Simple Linear Regression, because it show the relationship with the variables more accurately and you can know which one to discard, and which one to

The company maintains a minimum cash balance of at least $50,000 at the end of each month. All borrowing is done at the beginning of a month; any repayments are made at the end of a month.
There are a number of factors that contribute to the impact of the nursing shortage.
The null hypothesis that there is no relationship between the type of music a person listens to and his crime rate (p < .05).
There is a risk for a type 1 error in this study because of the multiple comparisons in this study.
There are multiple problems that have to be solved. The first problem is that Obama care is focusing on making sure everyone gets health insurance. First of all, you do not want anyone to force you to get something? No! Because you know what is right and wrong for you. Obama care is a force and I think everyone can make his or her own decision if they want insurance or not. From my own opinion, I think the only solution to this problem is to let people decide if they want to enroll or not. From this, money will be saved and people can decide for their best in health decision. If we all make a change to the issue, I think the society will be happier.
Disney used the character of Mickey Mouse and others to create movies that customers enjoyed like “Beauty and the Beast” while Pixar was producing made up animated characters to create films like “Cars” and “Wall-E”. Disney was creating animated movies but struggling to generate the amount of money Pixar was making on producing only one movie a year. Disney wanted to grow in creating more animated movies and decided to buy out Pixar in 2006 for $7.4 million dollars. (Barnes, 2008) According to Disney’s CEO Robert

Since the IBM ESA/390 mainframe is a client-server it needs to have software for employees to access data on server. McGraw-Hill purchased Remedy Action Request System software on run on their ESA/390 mainframe. Remedy Action Request (RAR) is software that stores user input in MYSQL table on the server. MYSQL tables include the source code which instructs the applications on how to cooperate with the users and the data. Action Request System has an open Application Programming Interface (API) which is a feature which allows users to create custom applications that talk directly to the Action Request System. Once a user enters customer information a Action Remedy ticket is created. A user can query the remedy action software for tickets numbers, case numbers, solutions, and/or how many times a issue have been reported.
credit balance is $5,678 and smallest at $1,864, resulting in a range of $3,814. The standard deviation is $924.11. This represents that in the aggregated comparison of credit balances of AJ Davis customers (in the sample set) a relatively small variation exists from the mean of $3,964.06. The median credit balance is $4,090.00, the median often provides a clearer picture of the overall

"There are several different kinds of relationships between variables. Before drawing a conclusion, you should first understand how one variable changes with the other. This means you need to establish how the variables are related - is the relationship linear or quadratic or inverse or logarithmic or something else" ("Relationship Between Variables ", n.d)
The $320,000, on the other hand, is a fixed cost associated with the proposed addition.
Biostatistics is important to study as undergraduates delve deeper into their studies of Biology and learn how the study of life is integrated into more than just their college-level science courses. Looking into the use of statistics at a scientific level at this stage of our education is preparing determined and enthusiastic students for the world of medicine as one day we will have to read and analyze sets of data and more than likely give the statistics of our patients’ issues. Biostatistics is allowing students to explore the world of medicine using a different approach, mathematically and critically. The purpose of this experiment was to determine if a significant multiple regression exists between my 3 quantitative variables, Weight, Height and Age and to determine the best regression model to use when making predictions.
