Question

In a fisheries researcher's experiment, the correlation between the number of eggs in the nest and the number of viable

(surviving) eggs for a sample of nests is r = 0.67.

The equation of the regression line for number of viable eggs y versus number of eggs in the nest x is y = 0.72x + 17.07.

For a nest with 140 eggs, what is the predicted number of viable eggs?

Definition Definition Relationship between two independent variables. A correlation tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
