Question

A scientist will be measuring the total amount of leaf litter in a random sample (n = 5) of forest sites selected without replacement from a population of 45 sites. The sites are labeled 01, 02, . . . , 45 and she starts at the beginning of the line of random digits and takes consecutive pairs of digits. Which of the following is correct?

Answer 1

The scientist will be using a random sample of forest sites to measure the total amount of leaf litter. The sample size is n = 5, and the sites are selected without replacement from a population of 45 sites.

Step-by-step explanation:

The scientist will be using a random sample of forest sites to measure the total amount of leaf litter. The sample size is n = 5, and the sites are selected without replacement from a population of 45 sites. The scientist starts at the beginning of the line of random digits and takes consecutive pairs of digits to select the sites. For example, if the random digits are 01, 23, 45, 67, 89, the selected sites would be 01, 23, 45, 67, and 89.
