Question

a greenhouse owner wants to test the effectiveness of a new fertilizer on african violets. she has 60 violet seedlings that were grown for 8 weeks. she wants to test the new fertilizer on 10 of the plants, and decides to use a random number table to select a simple random sample. which of the following correctly labels the population of violets? 00 - 60 01 - 60 0 - 60 1 - 60

Explanation:

When using a random number table for simple random sampling with \(n = 60\) items, we need labels of the same length. If we use single - digit labels (\(0 - 60\)), it's inconsistent in digit length. If we use \(1 - 60\), when generating two - digit random numbers from the table, numbers like \(01\) would be misinterpreted. Using \(00 - 60\) also has an extra number (\(60\) is two - digit and \(00\) is an extra non - existent plant if we consider \(60\) plants). The correct way is to use two - digit labels starting from \(01\) to \(60\) so that when we pick two - digit numbers from the random number table, each number in the range \(01 - 60\) corresponds to a unique plant.

Answer:

01 - 60
