For a school newspaper article, Cienna conducted a survey to find out students’ favorite subjects. She polled all the students in Mrs. Lopez’s advanced dance class. Why is her data likely to be skewed?

A: Honors dance students are more likely to enjoy dance than students in the general population, so dance may be overrepresented.

(if you get the question: "Raj polled 100 students in his class to compare the number of hours that teen boys and girls played video games each week. The results of his survey are shown below. Which gender shows greater variability in their playing time?

"

Then the correct answer is C: Girls show greater variability because the interquartile range for girls is 12 for girls but only 8 for boys.

)

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
