Solutions to Questions on Hypothesis Testing and Regression 1. A mileage test is conducted for a new car model‚ the “Pizzazz.” Thirty (n=30) random selected Pizzazzes are driven for a month and the mileage is carefully measured in each. The mean mileage for the sample is 28.6 miles per gallon (mpg) and the sample standard deviation is 2.2 mpg. Estimate a 95% confidence interval for the mean mpg in the entire population of Pizzazzes (you might need to round your answer a little bit to agree with mine)

noticeable linear relationship between page cost and median income. As for the scatterplot between page cost and percent male‚ the points appear to be scattered randomly because percent male does not affect page cost. 2 a) The multiple regression model is statistically useful overall because at least one independent variable is significant as shown below. H0: No linear relationship Ha: At least one X variable affects Y F = MSR/MSE = 5177553908/184850796 = 28.009

Abstract The essay looks at an empirical analysis into the main player and club characteristics that determine the transfer fee of a player. Using a competitive model and data from the Premier League spanning from July 2006 – September 2011‚ this paper will look to find and model the main factors that affect the price paid for a player. The paper will identify which characteristics directly affect the value of a transfer fee and the reasons behind these results. 1. Introduction 1.1 Outline
