Question

pablo is reading a book about birds. according to his book, the median weight of the group of ostriches studied was 220 pounds, and the interquartile range was 40.4 pounds. the median weight of the emus studied was 73 pounds, and the interquartile range was 26.8 pounds.

what can you conclude from these statistics? complete the sentences.

the ostriches studied typically weighed ____ the emus. also, the ostriches had ____ variability in weight compared to the emus.

Explanation:

Step1: Compare Medians

Median of ostriches: 220 pounds; Median of emus: 73 pounds. Since 220 > 73, ostriches' typical weight (median) is more than emus'.

Step2: Compare Interquartile Ranges (IQR)

IQR of ostriches: 40.4 pounds; IQR of emus: 26.8 pounds. Since 40.4 > 26.8, ostriches have more variability (IQR measures spread).

Answer:

The ostriches studied typically weighed \(\boldsymbol{\text{more than}}\) the emus. Also, the ostriches had \(\boldsymbol{\text{more}}\) variability in weight compared to the emus.
