time‚ one factor may be overbearing over others e.g. if inflation is too high or if system liquidity too much in surplus it may overshadow other parameters. We have covered 14 quarters to smoothen out any such impact. As we can see in the multiple regression analysis‚ the variables we have taken explain 80% of the movement in 10-year benchmark Gilt yield levels. The balance may be attributed to sentiments and other factors. Factors Influencing Movement of G-Sec. Yields: An Empirical Approach Introduction

Case Study: Managing Employee Retention Relationship Between Employee and Manager Tenure and Store Performance One of the first steps in analysis of the data is to make a comparison of the 10 most profitable stores and the 10 least profitable stores. Hart claimed that the manager and crew tenure in the most profitable stores was almost four times the level of that in the least profitable stores. This analysis is however based solely on the summary statistics for those ten stores in each category

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.
