estimates based on the ratio of the count on 

 the sample areas to the total count. 



The regression equation used in estimating 

 the total number of dead pups is: 



Y = 3.3322X-6, 198 



where 



X = count from sample areas 



Y = estimate of the total number of dead pups 



The estimate based on the ratio can be 

 derived by multiplying the count from the 

 sample areas by 2.998.
