output. Since OkunÕs original work‚ biased estimates of the Okun Coefficient on Unemployment‚ output gaps‚ and potential GNP have been reported by authors who mistakenly assume that unbiased coefficient estimates of the reverse regression are reciprocals of their direct regression analogues.

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

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)
