15 a Statistical Concepts Exercise 3 in chapter 21a .The null and alternate hypotheses are : Defect measure and lastingness level are independent ( multitude predicts desert grade : Defect rate and people are dependent ( slew does not predict break rateb .The race is every(prenominal) shifts at the plant . The exemplar is a random sample of results from 160 shifts at the plantc .Since the p-value of F statistic is slight(prenominal) than .001 . So we bath reject the null hypothesis at level of signifi crowd outce .05 and conclude that defect rate and mass are dependent . In other words , Volume signifi back endtly predicts defect rated .Yes , since the p-value of t statistics (beta coefficient ) is little than .001 , I sess reject the null hypothesis that the slope is 0e .
Yes , I can reject the null hypothesis that there is no linear relationship between the dependent and independent variable because the p-value is less than .001f .Yes , I can reject the null hypothesis that the creation correlation coefficient is 0g .Defect rate -97 .073 0 .027 (Volume -97 .073 .027 x 4200 16 .327The defect rate provide be 16 .327 -4 .92 ) on a day when the volume is 4200 units . The average will be 16 .327 for all eld with production volumes of 4200h .The estimates differ because on a single day there will be portion of error on the estimate . However , for all days the average error on the estimate will be zero15 b Data Analysis...If you w ant to get a dependable essay, order it on ! our website: OrderCustomPaper.com
