Question

Large herds of wild horses are a concern on some federal lands in the West. Researchers hoping to improve management of these herds collected data to see if they could predict the number of foals that would be born based on the size of the current number of adults in the herd. The research team recorded data on 38 herds of horses. Here is a scatterplot: Circle the word before or after each slash mark that makes each statement true. (a) Association is .. linear/nonlinear. (b) Correlation is .. weak/strong. (c) Correlation is .. negative/positive. (d) The number of foals decreases if the number of adults .. increases/ (e) R^2 has .. lesser/greater .. magnitude than the correlation, r.

Explanation / Answer

a) association is linear

b) corelation is weak

c) corelation is positive as slop of line to be fit is positive .

d) the number of foals decrease as the number of adults decrease

asr is positive

e) R^2 has lesser magnitude than r .

as 0< r< 1
