**Explanation:**
Gage R&R is an experiment conducted to understand whether the process variation is due to the measurement device, gage, or measurement. Hence, it is important to measure the parts in random order.

**Explanation:**
Test of equal variance is found under ANOVA in the Stat Menu.

**Explanation:**
This is a statistical analysis to assess the linear relationship between the Output variable, plotted on the Y-axis, and the input variable, plotted on the X-axis. In other words, when a relationship exists between the two variables, they are said to be correlated.

**Explanation:**
Repeatability is the ability of an operator to consistently repeat the same measurement of the same part, using the same gage, under the same conditions.

**Explanation:**
A One-way ANOVA compares the significant difference of two means.

**Explanation:**
Regression analysis determines the best fit line denoted by the regression equation. In this case, it means that 90% of the total variation is explained by the regression equation.

**Explanation:**
You can find Box-Cox transformation under Control chart in the Stat menu.

**Explanation:**
A contour plot is a graph used to study the possible relationship between three variables. It displays three-dimensional relationships in two dimensions on x, y and z scales.

**Explanation:**
Regression technique is used to analyze the relationship of X's and Y, where Y is the dependent variable and X is the independent variable.

**Explanation:**
You can find Bar chart under the Graph menu.

**Explanation:**
Null hypothesis always deals with the equality of different processes. There is 'no evidence of difference.' You never prove the Null Hypothesis; you only fail to reject it.

**Explanation:**
If we get the value of p<0.05, while carrying out ANOVA, it means the probability value of different levels of the factor is different, with 5% risk value.

**Explanation:**
Correlation and regression analysis interprets the relationships among variables. The correlation coefficient is a measure of linear association between two variables. Values of the correlation coefficient are always between -1 and +1.

**Explanation:**
You can find Quality tool under the Stat menu.

**Explanation:**
Separating the vital few or the trivial many, meaning 80% percent of effects is caused by 20% of causes; 80% of our time is taken by 20% of the activities we actually perform.

**Explanation:**
The ability of a gage, used by multiple operators, to consistently reproduce the same measurement of the same part, under the same conditions, is reproducibility.

**Explanation:**
You can find Scatter plot under the Graph menu.

**Explanation:**
The appropriate test is ANOVA, a statistical method in which the variation in a set of observations is divided into distinct components. In this case, the components are processing time and email categories.

**Explanation:**
The Session window displays the text output of your analysis, such as statistical test results and related notes or error messages. It also enables you to send the data from Minitab to MS Word and Passport.

**Explanation:**
Use of Kruskal-Wallis test determines if the medians of two or more groups differ when you have data that is skewed or symmetric.

**Explanation:**
You can find Sort option under the Data menu.

**Explanation:**
After determining the solution, we should assess the risks, identify if the chosen solution is cost effective, and if it can be executed.

**Explanation:**
You can find Paired t-test under the Stat menu.

**Explanation:**
A Contour Plot is a graph used to study the possible relationship between three variables. It displays three-dimensional relationships in two dimensions on x, y and z scales. Moreover, it enables you to predict the value of the output when a definite combination of two input processes is set.

**Explanation:**
You can find Measurement System Analysis option under the Assistant menu.

**Explanation:**
You can find Individual Plot value under the Graph menu.
