Question

OU's athletic director wonders if college grade point averages differ for male athletes in football, soccer, swimming, and baseball. To test this, he collects a sample of males from each sport, and compares the four mean scores to each other. Which test statistic is the most appropriate to use to answer this question? o Z of proportion O Zof x-bar Two-Independent Sample-t-test One-way ANOVA

Answer 1

Since there are more than 2 groups. So, One way ANOVA would be appropriate. ( 4th option is correct)

Z of proportion is wrong because here the parameter is not proportion but mean.

Z of x-bar is wrong becuase here standard deviation of populations are not known.

Two independent sample t test is wrong because here number of population not 2 rather 4.

Please support me by putting thumbs up. Thank you.
