Attempts: Score: 4 3. The distribution of the F-ratios Aa Aa Let's say that a researcher conducts a study with 4 groups, each with 7 participants. Fill in the degrees of freedom in the following ANOVA table. Source MS Between 39.62 8.70 Within 4.56 Total Use the following Distributions tool to find the boundary for the critical region at a 05 and a 01 To use the tool to find the critical F value, set both the numerator and the denominator degrees of freedom this will show you the appropriate F distribution. Move the orange line until the area in the tail is equivalent to the alpha level you are investigating. FDistribution Numerator Degrees offreedom 26 penontraor Degrees of Freedom 26

Explanation / Answer

between df =    3

within df = 24

F( 3,24) at 5% level of significance = 3.009

F(3,24) at 1% level of significance = 4.718

At 0.01 level of significance, Nul hypothesis can be rejected
