729. What is a chi-square Test?
- It is used for testing difference of two sample means when population standard Deviation is unknown but considered equal.
- It is a statistical tool used to test independence or dependence (or goodness-of-fit) between random variables taken from different populations.It is used for testing difference of a sample mean
- with a known population mean.It is used for testing difference of two sample means when population variance is unknown but considered equal.
730. What is a correlation?
- This statistical method is applied to test hypotheses among means from several populations.
- It measures the relationship of the inputs (x) on the output (y) of a process; shows the degree or extent of the relationship between two variables.
- It is leveling the workload across all processes in a cell or value stream to remove bottlenecks and excess capacity.
- A structured brainstorming tool designed to assist an improvement team in listing potential causes of a specific effect.
731. Which of the following statement/statements are true?

- Directional Multivariate
733. Which technique models impact on an output by the variation in two or more inputs
- Correlation Coefficient
- X-Y Diagram
- Linear Regression
- Multiple Regression
734. When is an F-Test used?
- When the data is not normally distributed.
- Used for testing the difference of three or more population means
- For testing the variance & only when sub groups are small.
- When there is a statistical change in the mean of the group before and after.
735. Which of the following is not a part of Data Analysis Tool?

- Coefficient of Determination
- None of the above.
- Coefficient of Correlation
- Linear Regression
737. Which of the following statement/ statements are true?
- All of the above.If the data points are close to the mean
- then the standard deviation is small.If P-Value <0.05
- data is not normalConfidence Intervals are the most prevalent form of interval estimation.
