How I do this in google sheets

Step 1 Design an experiment to determine how the initial density of juvenile snappers affects the mass of adult snappers. B. Randomize subjects among treatments and blocks to minimize bias caused by uncontrolled variables Now that you have chosen the treatments for our experiment, we need to assign fish to these treatments. Because each adult snapper can produce millions of offspring, we have more than enough juvenile snappers for our experiment. We will assign 100 juvenile snappers to treatment 1 (low initial density) and 200 to treatment 2 (high initial density). Although these fish were handled similarly up to the start of the experiment, we cannot assume they experienced identical conditions. Therefore, we should randomly assign these fish to the treatments. Directions: In your lab workbook, use the data in the tab for Step 1 to randomly assign fish to either treatment 1 or treatment 2. You will be uploading your Workbook with the completed table once you have completed all steps in the lab
