A researcher draws random samples of voters from four counties in California, with sample sizes of 27, 38, 34, and 25. On a IO-point scale measuring attitudes towards the current governor, the SSrorAL = 297 .33 and the SSBE"IWEEN = 38.22. What is the value of eta-squared? Is the probability less than a = .05 that the population means differ significantly across the four counties? Report the observed F ratio and critical value
