# Identify the sample, and suggest a population from which it was selected. Then classify the sample as simple, stratified, or systematic. Explain your reasoning.Greg divides his rookie baseball cards by teams. Then he randomly selects cards and records the players’ RBIs.

The sample is the cards selected by Greg.

The population is all cards.

The sample is stratified random samples.

See the step by step solution

## Step 1. Identify each sample, and suggest a population from which it was selected.

A sample is some portion of a larger group called the population.

Therefore, the sample is the cards selected by Greg and the population is all cards.

## Step 2. Classify the type of sample.

A stratified random sample is a sample in which the population is first divided into similar, nonoverlapping groups. A random sample is then selected from each group.

As Greg firstly divides the rookie baseball cards by teams and then he selects the cards. That is population is first divided is similar groups and then a random simple sample is selected. Therefore, the sample is stratified random samples.
