Statistic 15b C

15 a Statistical Concepts Exercise 3 in chapter 21a .The null and alternate hypotheses are : Defect measure and chroma level are independent ( multitude predicts desert prise : Defect rate and people are dependent ( muckle does non predict mistake rateb .The race is every(prenominal) shifts at the plant . The smack 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 volume are dependent . In other words , Volume signifi mickletly predicts defect rated .Yes , since the p-value of t statistics (beta coefficient ) is little than .001 , I puke reject the null hypothesis that the slope is 0e .

Yes , I can reject the null hypothesis that there is no one-dimensional relationship between the dependent and independent variable because the p-value is less than .001f .Yes , I can reject the null hypothesis that the existence 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 geezerhood with production volumes of 4200h .The estimates differ because on a single day there will be recover of error on the estimate . However , for all days the average error on the estimate will be zero15 b Data Analy sis...If you want to get a spacious essay, ! order it on our website: OrderCustomPaper.com
