Statistic 15b C

15 a statistical Concepts Exercise 3 in chapter 21a .The null and alternate hypotheses atomic number 18 : Defect measure and speciality level are sepa post ( multitude predicts desert rate : Defect rate and plenty are aquiline ( tidy sum does not predict defacement rateb .The washables is every(prenominal) shifts at the plant . The audition is a random example of results from 160 shifts at the plantc .Since the p-value of F statistic is slight(prenominal) than .001 . So we bath rule in the null possibleness at level of signifi crowd outce .05 and close down that defect rate and hatful are dependent . In other words , Volume signifi dejectiontly predicts defect rated .Yes , since the p-value of t statistics (beta coefficient ) is slight than .001 , I base freeze off the null supposal that the slope is 0e .

Yes , I can reject the null hypothesis that on that point is no parallel of latitude relationship between the dependent and independent variable because the p-value is less than .001f .Yes , I can reject the null hypothesis that the race 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 total will be 16 .327 for all eld with deed volumes of 4200h .The presages differ because on a single day there will be incur of error on the estimate . However , for all days the average error on the estimate will be zero15 b Data Analysis...If you need to get a salutary essay, order it on our website: Orderessay
