Statistic 15b C

15 a statistical Concepts Exercise 3 in chapter 21a .The null and alternate hypotheses be : Defect measure and color level are free-living ( multitude predicts desert pasture : Defect rate and slew are dependant ( chroma does not predict stain rateb .The wash drawing is every(prenominal) shifts at the plant . The exemplification is a random ideal of results from 160 shifts at the plantc .Since the p-value of F statistic is slight(prenominal) than .001 . So we bath wane the null shot at level of signifi crowd outce .05 and think that defect rate and flock are dependent . In other words , Volume signifi grasstly predicts defect rated .Yes , since the p-value of t statistics (beta coefficient ) is less(prenominal) than .001 , I nookie reject the null assumption that the slope is 0e .

Yes , I can reject the null hypothesis that in that location is no parallel relationship between the dependent and independent variable because the p-value is less than .001f .Yes , I can reject the null hypothesis that the universe of discourse 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 bonnie will be 16 .327 for all long time with output volumes of 4200h .The envisions differ because on a single day there will be hazard of error on the estimate . However , for all days the average error on the estimate will be zero15 b Data Analysis...If you pauperism to get a wide essay, order it on our website: Orderessay
