Distribution of Song Length for 23 Rock and 23 Rap Songs Variable Rap Song Length- Rock Song Length 2.5 3.5 4.5 O a. No, inference using the t-distribution would not be appropriate because there are no outliers present. O b. No, inference using the t-distribution would not be appropriate because the histograms are both extremely skewed. O c. No, inference using the t-distribution would not be appropriate since we do not know the population standard deviations. Od. Yes, inference using the t-distribution would be appropriate.
