Assignment 2- Database Modeling and Normalization Dr. Amir Afzal Strayer University- CIS 515 August 7‚ 2012 Abstract Selling high end electronics is big business and being a commissioned employee in that field if your sales are up means big money. Prices for electronics range from the low hundreds into the thousands. It really depends on the person style‚ specifications they are looking for‚ trust in the brand‚ and the depth of their pockets‚ how much a person is willing to spend for

created on a graph when using a frequency distribution method for a set of data‚ splitting the mean symmetrically. There is a big difference between standard deviation and the bell curve! Standard deviation shows the difference in variation from the average; the bell curve‚ also normal distribution or Gaussian distribution‚ shows the standard deviation and is created by the normal or equal distribution of the mean among either half. The bell curve is an important distribution pattern occurring in many

and that units left unsold at the end of the season were sold at a loss that average 8 percent of wholesale price. Therefore‚ the stock out probability equal to 8%/(24%+8%)=25% so there are 75% probability of being less than mean+0.67*SD (standard deviation). According to z table‚ z equal to 0.67 when probability is 0.75. Therefore‚ we can calculate quantity for each style include the risk of stock out by using formulate Q*=mean+z*SD. Therefore‚ we can get the maximum order units for each style in order

Most professional baseball pitchers can throw a fastball over 145 km/h (90 mph). This gives the batter less than half a second to read the pitch‚ decide whether to swing‚ and then try to hit the ball. No wonder hitting a baseball is considered one of the hardest things to do in sports! 1. What

First Question It is common for houses in cold climates to be build out of wood‚ because the cold climate doesn ’t weather wood‚ thus providing more longevity to the house; wood helps in trapping heat so the heat that is emitted from he lights in the houses during winter is captured by wood and stored in it‚ works as cold insulator‚ allows building layered walls that helps in installing a layer of cold insulator within the walls References: [1] http://home-and-constuctions.blogspot.ca/2010/02/wooden-houses
