Solution Steps

To determine the type of sample, we need to analyze how the sample is selected. In this scenario, an entire team is selected at random, and all players on that team are tested. This is characteristic of a cluster sample, where a whole group (or cluster) is chosen randomly, and all members of that group are included in the sample.

Step 1: Identify the Sampling Method

In this scenario, a team is selected at random, and all 26 players on that team are tested for performance-enhancing drugs. This method involves selecting a whole group (or cluster) and including all its members in the sample.

Step 2: Classify the Sample Type

Given that the entire team is chosen as a single unit and all players are tested, this sampling method is classified as a cluster sample.

Final Answer

The answer is a cluster sample, so we have \\(\boxed{\text{cluster sample}}\\).

In the Mitosis simulation, we studied the effects of the drug paclitaxel on cultured cells. Based on your examination in the simulation you were able to conclude: Paclitaxel had no effect on cell division Paclitaxel inhibits cell division Paclitaxel was not studied in the simulation Paclitaxel accelerates cell division
