36. Which of the following is(are) TRUE about the predicted model?*
2 po
1. For every am increase in length, the weight of fish increases by 30.846 grams.
II. Weight is linearly dependent on length, at 5% level of significance.
OA. I only
B. II only
C. Both I and II
D. Neither I nor II

Transcribed Image Text:For number 36: To provide evidence on the classic length-weight-relationship
(LWR) model in the fishery literature, a model was created wherein it is of interest
to predict the weight (in grams) of a fish based on its length (in cm). R outputs
are provided below:
