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 about three times as much as the emus. also, the ostriches had less variability in weight compared to the emus.

Explanation:

Step1: Compare median weights

The median weight of ostriches is 220 pounds and of emus is 73 pounds. Since 220 > 73, ostriches typically weighed more.

Step2: Compare inter - quartile ranges

The inter - quartile range of ostriches is 40.4 pounds and of emus is 26.8 pounds. Calculate the ratio: $\frac{40.4}{26.8}\approx1.5$. So the variability in weight of ostriches is more than that of emus.

Answer:

Ostriches typically weighed more, and the variability in weight of ostriches was more than that of the emus.
