Question

A zoologist a population of 800 rabbits. He tags 160 rabbit at random, of which 37 have blue eyes. Based on this data, about how many rabbits in the population have blue eyes.

Answer 1

185 rabbits

Explanation:

800 \ 160 = 5

So he tagged exactly 1/5th of the rabbits

Which means theoretically the amount of rabbits with blue eyes in total would be 5 times the number from the data

5 x 37 = 185

Answer 2

Answer:185

Explanation:

Population size = 800

Sample size = 160

Number of blue-eyed rabbit in sample = 37

The proportion of blue-eyed rabbit in the sample is :

p = number of blue eyed rabbit / sample size

p = 37 / 160 = 0.23125

Estimated number of blue eyed rabbit in population :

p * population size

0.23125 * 800

= 185
