What Conclusion Is Justified If an F-Ratio of

question 20

Multiple Choice

What conclusion is justified if an F-ratio of .93 is obtained in a one-way ANOVA?

• A) The null hypothesis is accepted, with the chance of this conclusion being wrong equal to the α level selected.
• B) Since the numerator and the denominator of the F-ratio both estimate the same value, a result of less than 1 is not possible; hence, a mathematical error must have occurred.
• C) There is no significant difference among treatment means, and sampling error caused the F-ratio to be less than 1.
• D) Acceptance of the null hypothesis is called for, but the F-ratio of less than 1 suggests a probable Type II error.
