understanding the correlation between them we need to do a correlation analysis and also to get a deeper understanding in what really affects the credit balances in AJ department stores we need to do a regression analysis to help us get to 100% confidence in making the right decisions. We did a scatter plot to help us understand the relationship between credit balance and size and we found that we can see there is a direct relationship with credit balance. We can expect a decrease of -2.3 and we

Various procedures have been developed to compute good control limits. This paper proposes construction of Range chart by considering a Pareto distribution of IV kind. The cumulative distribution function of sample range from their distribution is derived. The percentiles of the distribution of range are worked out and are used to construct the control limits. The performance of the control chart is compared with that of gamma based control chart. Interval estimation for the scale parameter is

part two we calculated the sample proportions for each color, the mean number of candies per1.69oz bag, created a histogram for the number of candies per bag, use Excel to compute the descriptive statistics for the total number of candies per bag and summarize the information. In part three we located the 95% confidence interval for the proportion of blue, orange, green, yellow, red and brown. For part four we tested claims for percentages of each color. In the final part of the project we tested

hypothesis that contradicts the null hypothesis, and set the alpha which will help determine the probability of an error. Step three is where the sampling distribution method is selected. This is where the test statistics are specified. In step four, we compute the test statistic by using a formula and coming to a result. The final step, step five, is where a decision is made and the results are interpreted. If the result is greater than the alpha level set in step two, we can assume the null hypothesis

Simulation Lecture Notes and the Gentle Lentil Case General Overview of the Case • What is the decision problem presented in the case? • What are the issues Sanjay must consider in deciding among the alternative choices? 1 Accounting Model of Gentle Lentil’s Monthly Earnings What are the monthly fixed costs? L = labor costs (between $5,040 and $6,860) U = rent, utilities, other unavoidable costs = $3,995 What are the monthly variable costs? F = food costs M = number of meals served

Avio Alice - Project Lead Leo – Hotel manager Working with Data: • Before starting any type of formal data analysis, we should try to get a preliminary sense of the data • Identify trends, group data Histograms -A histogram shows us where the data tend to cluster Skewd right – mean is higher than median Outliers: -Values that fall outside of the trend -Understand where the outlier comes from -Leave it or remove it Central Value Data • Mean – Average o Most common

Stats/Modelling Notes Introduction & Summary Computer system users, administrators, and designers usually have a goal of highest performance at lowest cost. Modeling and simulation of system design trade off is good preparation for design and engineering decisions in real world jobs. In this Web site we study computer systems modeling and simulation. We need a proper knowledge of both the techniques of simulation modeling and the simulated systems themselves. The scenario described above
