Which of the Following Is the Correct Interpretation of the Fisher's

question 31

Multiple Choice

Which of the following is the correct interpretation of the Fisher's 100(1 - α) % confidence interval for μ_i - μ_j?

• A) If the interval includes the value zero,the null hypothesis,that H₀: μ_i - μ_j = 0,is rejected for at α level of significance.
• B) If the interval does not include the value zero,the null hypothesis,that H₀: μ_i - μ_j = 0,is rejected at 100(1 - α)% level of significance.
• C) If the interval does not include the value zero,the null hypothesis,that H₀: μ_i - μ_j = 0,is rejected at α level of significance.
• D) If the interval includes the value zero,the null hypothesis,that H₀: μ_i - μ_j = 0,is rejected at 100(1 - α)% level of significance.

Definitions:

Factorial Research Designs

Experimental designs that allow researchers to examine the effects of two or more independent variables on a dependent variable, as well as the interaction effects between variables.

Interaction Effect

The effect on a dependent variable that arises from the combination of two or more independent variables, rather than from any single variable.

Dependent Variables

Variables in an experiment or study that are expected to change as a result of changes in the independent variable.

F-Ratio Statistic

The F-ratio statistic is utilized in statistical analysis, specifically ANOVA, to compare the variance between groups to the variance within groups, aiding in understanding if the means between two or more groups are significantly different.
