CHAPTER 7 THE TWO-VARIABLE REGRESSION MODEL: HYPOTHESIS TESTING QUESTIONS 7.1. (a) In the regression context‚ the method of least squares estimates the regression parameters in such a way that the sum of the squared difference between the actual Y values (i.e.‚ the values of the dependent variable) and the estimated Y values is as small as possible. (b) The estimators of the regression parameters obtained by the method of least squares. (c) An estimator

Case No 7 Tiresome Tire I Introduction: This case is about Hypothesis Testing‚ there is a tire manufacturing company which is producing tire with the strength 2800 pound per square inch (psi)‚ we have to test Null Hypothesis i.e. H0 : u> 2‚800 psi‚ where u is the mean strength of large batch of tire and population SD is 10 psi. Calculation: We have to test Null Hypothesis based on given information. Type I error will result in the rejection of a large number of good tires. Type II error
