Question

data were collected on life spans (in years) and gestation lengths (in days) for 62 mammals. a scatterplot of life span versus length of gestation is shown below.
(a) what type of an association is apparent between life span and length of gestation?
negative
positive
no association
(b) what type of an association would you expect to see if the axes of the plot were reversed, i.e., if we plotted length of gestation versus life span?
negative
positive
no association
(c) are life span and length of gestation independent? explain your reasoning.
life span and length of gestation select independent. mammals with longer gestation periods tend to have a select life span.

Explanation:

Step1: Analyze the scatterplot for (a)

Observe the trend: as gestation length (x[SSE onError error]
