A oneway withingroups ANOVA on 3 and 28 degrees of freedom r

A one-way within-groups ANOVA on 3 and 28 degrees of freedom results in an F statistic of 3.94. What decision should be made about the hypothesis based on this statistic?

Solution

Consider Level of significance 0.05

P-value using Excel is 0.0183

Since the P-value is less than the level of signifcance 0.05 we reject the null hypothesis and conclude there are differences among the levels of the independent variable.

So the correct answer is (c)
