Julie wants to know if adding calcium fertilizer to tomato plants will prevent a disease of tomato plants called blossom-end rot. she uses 10 tomato plants. she put 5 plants in a sunny part of the garden and gives each one calcium fertilizer once a week. she places the other 5 plants in a shady part of the garden and gives them calcium fertilizer twice a week. she observes the 10 plants for 3 months to see if the fertilizer prevent blossom-end rot. based on her experiment design, julie's results are probably not reliable.
