The manager of a convenience store wishes to determine how many cartons of eggs are damaged in shipment and delivery. For ten shipments of 1000 cartons of eggs, she examines every 50th carton to see how many cartons contain cracked eggs.

Identify the population and the sample

a.

population: 1,000,000 cartons of eggs


sample: every 50th carton in each shipment

c.

population: 10 shipments of 1000 cartons of eggs


sample: every 50th carton in each shipment


b.

population: 1,000,000 cartons of eggs


sample: the 50th carton of eggs

d.

population: 10 shipments of 1000 cartons of eggs


sample: the 50th carton of eggs

Answer 1

10 times 1000 is 10,000, not 1,000,000. So, option A and B can be immediately eliminated, and since the question say every 50th carton, I think the answer is C.

Answer 2

Option c. Population: 10 shipments of 1000 cartons of eggs

sample: every 50th carton in each shipment.

Explanation:

First we find out population :

For ten shipments of 1000 cartons of eggs. In other words in each 10 shipments there are 1000 cartons of eggs.

Therefore, 1000 × 10 = 10,000 cartons of eggs.

Population : 10,000 cartons of eggs

Now it is given that she examines every 50th carton to see how many cartons contain cracked eggs.

Hence, Sample would be every 50th carton in each shipment.

In option a and b given cartons of eggs are 1,000,000, so they would be eliminated and in option d it is given that sample is only 50th carton of eggs

Therefore, option c would be correct.
