You have 100 seedling plants at each of 12 different nurseries to use in your experiment. Your experiment should run six months in length. Outline the details of your experiment. How many subgroups would you need to complete the experiment? Describe a strategy for randomization that fulfills your previous answer: Discuss what might be a possible response variable. In addition, you should identify at least one confounding variables and discuss a method of controlling for one of this variable.

Please help me with these 2 questions.Help is very much appreciated!!

2. A farm cooperative has asked you to design an experiment that measures the effects of light
exposure on the growth of tulips in the Skagit Valley of Washington State.
You hypothesize that tulips exposed to more direct light will grow at a faster rate than those
exposed to less light. You also wonder whether the effects of light exposure persist when you
control for the amount of moisture the plants receive. You want to create a randomized
comparative design that considers three factors with the following levels:
Amount of Light Exposure (0 hours a day, 3 hours a day, 6 hours a day, 9 hours a day)
Amount of Moisture Exposure (1 hour a day, 3 hours a day, 5 hours a day)
You have 100 seedling plants at each of 12 different nurseries to use in your experiment.
Your experiment should run six months in length. Outline the details of your experiment.
How many subgroups would you need to complete the experiment?

Choosing the Design of an Experiment Assignment
Complete each part of the questions. Since the goal of many of these questions is to specify the details of
a proposed experimental design, your descriptions must be clear and specific.
1. The Academy of Sports Medicine Physicians is interested in determining whether a new
training regimen will help long-distance runners improve their performance in marathons.
This organization comes to you for some advice on how to design an experiment to test
whether this new regimen is more effective than the standard regimen. You have access to a
sample of long-distance runners on the track teams at ten different universities. You hope to
conduct the experiment over the course of two years because the regimen takes a long time to
learn and because you want to include new runners in the sample as they join the track team.
You also believe that the effect of the regimen on performance may differ for men and women.
Your challenge is to design an experiment that uses a randomized approach to measure the
effect of the new regimen on performance.
Remember, your design should take into account your concerns about different effects for men
and women and should be set up so that new subjects can be properly included in the
experiment. Create an experiment that will address these concerns.
Pay particular attention to the factors, explanatory and response variables, any blocks or
matching characteristics, and the treatment conditions used in the experiment.
You may want to create a diagram that summarizes your experimental design (this is not
required.)
