Question

PLEASE HELP FAST!! IT IS URGENT!! A biologist wants to determine if different temperatures (15°C, 25°C, or 35°C) and amounts of sunlight (partial or full) will affect the growth of plants. He will test each combination of temperature and sunlight by randomly assigning 15 plants to each of the combinations. What type of sampling is described in this study?

one sample
paired data
two samples
more than two samples​

Answer 1

The type of sampling described in this study is more than two samples. The biologist is testing three different temperatures and two amounts of sunlight, which add up to six different combinations. Each combination is being tested with 15 plants each, for a total of 90 plants in the sample.
