A study of road rage asked separate random samples of 596 men and 523 women about their behavior while driving. Based on their answers, each respondent was assigned a road rage score on a scale of 0 to 20. Are the conditions for performing a two-sample ttest satisfied?
A. Maybe; we have independent random samples, but we need to look at the data to check Normality.
B. No; road rage scores in a range between 0 and 20 can’t be Normal
C. No; we don’t know the population standard deviationsd.
D. Yes; the large sample sizes guarantee that the corresponding population distributions will be Normale.
