Textbook Question
Chapter 14, Problem 1E

As part of a sixth-grade class project the teacher brings to class a large jar containing 200 gumballs of two different colors: red and green. Andy is asked to draw a sample of his own choosing and estimate the number of red gumballs in the jar. Andy draws a sample of 25 gumballs, of which 8 are red and 17 are green. Use Andy’s sample to estimate the number of red gumballs in the jar.

Expert Solution & Answer
Check Mark
To determine

To find:

The number of red gumballs in the jar.

Answer to Problem 1E

Solution:

The numbers of red gumballs in the jar are approximately 64.

Explanation of Solution

Given:

Total numbers of gumballs in a jar are 200. Andy draws a sample of 25 gumballs, of which 8 are red and 17 are green.

Formula used:

Single- Sample Estimation Method:

knNP...(1)

Where, P is the size of the general population, N is the size of the subpopulation, n is the size of the sample, and k is the number individuals belong to the subpopulation.

Calculation:

From the given information, substitute 200 for P, 25 for sample size n, 8 for k in the equation (1) as,

knNP825N200N8×20025

Further simplify.

N=160025=64

Conclusion:

Thus, the numbers of red gumballs in the jar are approximately 64.
