You and others have worked on a Kaizen team and you feel that you have reduces the standard devaition of the filling process. You have randomly selected a sample of 150 containers and weighed them. The standard deviation that you found was 0.105 ounces. At a 95 percent level of confidence can you prove that the standard deviation has moved from 0.12 ounces. What is the null equal? (Two decimals) (Remember the software uses variance.) What is your alternative?[ () What is the sample size? (whole number) What is the level of significance?[ (Two decimals) What are the degrees of freedom? (no decimals) What is the chi-square test statistic?[ (no decimal) What is the critical value? (no decimal) What is the p-value? (Four decimals) At the 95 percent confidence level, do you "reject the null or fail to reject the null"?[ (reject or fail to reject) At the 95 percent confidence level, did you appear to improve this process?
