Wesley collects data on 1,000 crabs and uses the data to develop the following least-squares regression line where x is the age of the crab in months and y is the predicted value of y, the size of the male crab in cm. y^= 0.5226x + 8.1312 al places. What is the value of y when a male crab is 23.0736 months old? Provide your answer with precision to Scroll policy terms of use contact us help

Explanation / Answer

Solution:

Given reggression line,

y = 0.5226x + 8.1312

the predicted value of y when the crab is 23.0736 months old

y = 0.5226 (23.0736) + 8.1312

y = 20.1895

The value of y is the predicted size of the crab when it is 23.0736 months old
