THE CHI-SQUARE GOODNESS-OF-FIT TEST The chi-square goodness-of-fit test is used to analyze probabilities of multinomial distribution trials along a single dimension. For example‚ if the variable being studied is economic class with three possible outcomes of lower income class‚ middle income class‚ and upper income class‚ the single dimension is economic class and the three possible outcomes are the three classes. On each trial‚ one and only one of the outcomes can occur. In other words‚ a family

We are asked to determine if gender influences the choice of a major. Conducting a Chi Square Test of Independence allows us to draw a conclusion. Two variables that are categorical is required to complete a Chi Square Test of Independence (Mirabella‚ 2011). The purpose of this test is to determine if variables are independent or dependent from one another. To see the relationship between two variables‚ we are to use cross tabulation. Cross tabulation is when we display information for two variables

Mangrobang‚ Jonathane Submitted to: Prof. Ernesto Adorio January 2014 Description: Our instructor instructed to put tabulate the Binomial Distribution for various n given the values of p which are (0.1‚ 0.2‚ 0.3‚ 0.4‚ 0.5‚ 0.6‚ 0.7‚ 0.8 and 0.9). The binomial distribution is the discrete probability distribution of the number of successes

Chi-Square Homogeneity Test The purpose of a chi-square homogeneity test is to compare the distributions of a variable of two or more populations. As a special case‚ it can be used to decide whether a difference exists among two or more population proportions. For a chi-square homogeneity test‚ the null hypothesis is that the distributions of the variable are the same for all the populations‚ and the alternative hypothesis is that the distributions of the variable are not all the same (i.e.‚ the

Module 5 Create a car saying (Bumper Sticker) or a Road Sign (Billboard) that would describe one main point you learned in Module 5. This is an example of a bumper sticker from a former student: ““Driving the right speed is always a good deed. Enjoy your ride and don’t collide!” 1. What would yours say? Fasten your seat belts‚ It Helps. 2. How would it look? It would be a billboard of a family and the driver and the backseat passengers have on seat belts but the front passenger doesn’t 3. Now

If you developed an instructor evaluation form‚ which characteristics would you would want to include? Why? Knowledgeable- An instructor should be knowledge about the content covered in the course. Often times an instructor may have to elaborate on the content covered course material in order to give to student a better understanding. Communication – It is important that the instructor is able to communicate efficiently with the students. It is important for the instructor to provided constructive

MATH533: Applied Managerial Statistics PROJECT PART C: Regression and Correlation Analysis Using MINITAB perform the regression and correlation analysis for the data on SALES (Y) and CALLS (X)‚ by answering the following questions: 1. Generate a scatterplot for SALES vs. CALLS‚ including the graph of the "best fit" line. Interpret. After interpreting the scatter plot‚ it is evident that the slope of the ‘best fit’ line is positive‚ which indicates that sales amount varies directly
