Step 1 :Given the lengths of Tito and Lydia, the mean lengths and the standard deviations of their respective populations, we need to calculate the z-scores for Tito and Lydia.
Step 2 :The z-score is a measure of how many standard deviations an element is from the mean. To find the z-score, we subtract the mean from the element and then divide by the standard deviation.
Step 3 :First, calculate the z-score for Tito. Subtract the mean length of the male shark population from Tito's length, then divide by the standard deviation of the male shark population. This gives a z-score of approximately 1.48.
Step 4 :Next, calculate the z-score for Lydia. Subtract the mean length of the female shark population from Lydia's length, then divide by the standard deviation of the female shark population. This gives a z-score of approximately 1.12.
Step 5 :Finally, compare the z-scores of Tito and Lydia. The shark with the higher z-score is larger relative to its population. In this case, Tito has a higher z-score, so Tito is larger relative to its population.
Step 6 :Final Answer: The z-score of Tito's length is approximately \( \boxed{1.48} \) and the z-score of Lydia's length is approximately \( \boxed{1.12} \). Therefore, relative to its population, \( \boxed{\text{Tito}} \) is larger.
