September 29‚ 2013 Estimation Paper In our group we have me‚ Kelip and J.R.‚ and individually we both played our separate parts. Even though we did not have a perfect time to really meet up because of unscheduled events‚ I still think we managed to work as a team. To start off‚ the question that we chose to find an estimation answer on was “How many softballs can fit in our lecture room?” The first couple of class time was spent on J.R. and Kelip measuring the walls and indents of the classroom

1. Affirmative Action destroys the idea of meritocracy and students should be chosen based on their intelligence instead of their race or gender. “At the University of Wisconsin‚ the median composite SAT score for blacks who were admitted was 150 points lower than for whites and Asians and the Latino median SAT score was 100 points lower”. This quote shows how Affirmative Action destroys the idea of meritocracy and applicants are mainly chosen on someone’s race not intelligence. (http://brandongaille

each of the variables specified in the model from the years 2003 to 2005. The question that I will be answering in my regression analysis is whether or not wins have an affect on attendance in Major League Baseball (MLB). I want to know whether or not wins and other variables associated with attendance have a positive impact on a team ’s record. The y variable in my analysis is going to be attendance for each baseball team. I collected the data for each team ’s average attendance for 2003-2005

History In the late 1500’s‚ Spanish explorers‚ led by Don Juan Onate‚ founded the first settlements near the Rio Grande (Las-Cruces.org). Explorers created a road that ran from Mexico City to Santa Fe that was named El Camino Real‚ Royal Road‚ in their desire to find treasure in the legendary Seven Ancient cities of gold (City-Data.com‚ 2009).
