You have been on the job for two months and you are just now finding the time to analyze all of the processes your team goes through when they set up and tear down an event site. A member of your team has just walked you through the post-event process of cleaning, transporting, and storing the tables used during banquet events. You discover that following each event, tablecloths are always removed and all tables are polished before being folded and transported. It is obvious to you that the step of polishing the tables is: A source of customer satisfaction A B C D A B C D A B C D A B C D A https://www.coursehero.com/file/10258065/SIX-SIGMA-GREEN-BELT-Test-Week-4/ This study resource was shared via CourseHero.com

Introductory Business Statistics

What are conditions for a binomial distribution? I. Continuous data  II. It is two-state (success/failure, defective/not defective, etc.)  III. The trials are independent  IV. The probability of success on every trial is the same  A I, II, and III only B I, III, and IV only C I and III only D None of the choices are completely correct A normal probability plot could be used to determine  A Process capability C The level of confounding D Resolution Common-cause variation is normally I. Expected II. Random III. Assignable  A I only B II only C III only D I and II only The type of measurement scale that can classify objects, rank objects, has equal intervals and has a true zero point is  A Nominal B Ordinal C Interval D Ratio Which of the following describes the F-Distribution?  A It is the ratio of two sample variances B It assumes both populations are normally distributed C F-statistic is always positive D All of the above This distribution is used to analyze data when there is an equally likely chance of being above or below the mean for continuous data wh curve.  A F-distribution B Student-t C Normal D Hypergeometric The formula for standard deviation for samples is  A B C D On a normal probability plot, if the plotting of point percentages are ___________, the process is said to be "normally distributed."  A curvilinear B lognormal C exponential D straight The assumption that experimental results are due to chance alone is called _________.  A The alternative hypothesis B Significant results C The test statistic D The null hypothesis There is only one correct answer to each of these test questions. What is the probability that you will select all of the next four answers c know nothing about the subject matter (and there are no obvious ridiculous choices)?  A 0.75 D 0.0039 If an operator stops the process often, takes a sample, and then adjusts the process to the center over and over again, what happens? I. Variation increases II. Variation decreases III. The process will appear more and more like a bell shape as he or she goes IV. The process will appear less like a bell shape as he or she goes  A I and II are true B II and III are true C II and IV are true D I and IV are true The normal probability plot is a plotting of  B Standard deviation values D Point percentages When you have a bell-shaped curve, none of the five Ms or one P are  A Influencing or affecting the process in any way B Acting in a random fashion C Unduly influencing the process Which distribution is used to test hypotheses about two population variances?  A Hypergeometric distribution B Standard normal distribution C Chi-Square distribution D F-distribtuion A Z-value of 1.16 is _____ under the normal curve.  A 72% B 12% C 37% D 88% A run chart is more like  A The camera that takes still shots than it is like a camcorder that records movies B The camcorder that records movies than it is like a camera taking still shots C A snapshot of the process at a moment in time than it is like a motion picture over time D A scatter diagram than it is like a Pareto chart By looking at a Box Plot, how do you know that your distribution is skewed?  A Because there are outliers B The line inside of the box itself is not centered C The smallest value is less than the 25th percentile D The smallest value is greater than the 25th percentile In hypothesis testing, when performing a right-tailed test we reject the null hypothesis if  A The test statistic is larger than the critical value
