Question

The manager of an SAT review program wonders whether average SAT scores differ depending on the ethnicity of the test taker. Thirty test scores for four ethnicities are collected. A portion of the data is shown in the accompanying table; the entire data set, labeled SAT_Ethnicity, can be found on the text website.


At the 5% significance level, can we conclude that the average SAT scores differ byethnicity?
