Case Study 2-The Case of Jesica Santillon Effective communication requires messages to be conveyed clearly to the appropriate parties, but along the way there are many communication barriers that can create misunderstandings and misinterpretations of the intended message (Burns, Bradley & Weiner, 2012). Such misunderstandings and misinterpretations are apparent in the case of Jesica Santillon. This case study will identify the social and cultural barriers that may have made it difficult for

on the sales forecast for next year. Ted has previously noticed forecast errors are not inexpensive and must determine the sales forecast for 2008 based on the sales from the previous four years (2003-2007) as precisely as possible. After running the following methods: Holtz-Winters Additive Model, Regression with Times Series, Regression with Economic Factors, and Holtz-Winters Multiplicative Model. Built on the data and error the most appropriate method of forecasting is Regression with Economic

existed in the past will continue to exist in the future. 2. Forecasts are not perfect and their results usually differ from predicted values. Allowances should be made for forecast errors. 3. Forecasts for groups of items tend to be more accurate than forecasts for individual items because forecasting errors among items in a group usually have a canceling effect. Opportunities for grouping may arise if parts or raw materials are used for multiple products or if a product or service is demanded

Acceleration Due to Gravity Tushar Agarwal 17st November 2014 Aim-In this experiment I will be calculating the value of gravity by the drop of the ball. I will be measuring the distance and finding out the time . Distance will be changed however the size of the ball and the type of the ball will remain constant , The time will be then give me the value of gravity by the suvat equation ,where acceleration will be the subject . Background Knowledge.For an object to move, a force

Lab #4: Kinematics - Velocity and Acceleration Introduction: The purpose of this lab is to discover and understand the relationships between position, velocity, and acceleration. Additionally, constant/uniform acceleration due to the force of gravity will be examined to find possible mathematical relationships to position and velocity. Velocity and acceleration are changes in position and velocity, respectively, with regards to time. This change can be shown mathematically in calculus derivatives:

been affected by factors such as errors while recording the data or participants giving wrong answers. Measurements Measurement refers to an amount of or extent of something. This element plays a role in the achievement of correct answers to a problem. From the article on prospective prediction of husband’s marital aggression within newlywed couples, the measurements taken on the various variables considered in the research may have had some errors due to human error during collection of the data

1. In a manufacturing process a random sample of 36 bolts manufactured has a mean of 3 inches w/ a standard deviation of .3 inches. What is the 99% confidence interval for the true mean length of the bolt? Confidence interval = [pic] = (2.87, 3.13) 2. When the population is normally distributed, population standard deviation σ is unknown, and the sample size is n = 15; the confidence interval for the population mean σ is based on the ________. Sample standard deviation, s. 3. Suppose
