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 t test 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 cant be Normal.
(c) No; we dont know the population standard deviations.
(d) Yes; the large sample sizes guarantee that the corresponding population distributions will be Normal.
(e) Yes; we have two independent random samples and large sample sizes.
