For quetions i and 2, consider the following minitab generated boxplots of coagulation timeo (in seconds) for sample of blood drawn from animals receiving thre different diets. denoted 1, 2 and 3. dl. ct" r. "": -----i. --;-=--------i--- : : consider the following 3 statements, and circle the correct answer below, the animal that had the longest coagulation time was given diet 3. Ii) the great st variability in coagulation times occurs with diet 3. Iii) diet i show evidence of right skewness aod diet 2 shows evidence of teft skewnes. Ii) diet t has the greatest upper (third) quartile of the 3 diets. Iii) we can deduce tbat the mean for diet i is less than 62 eecond6: only i ie true, aii are true.
