Choose the best scientific design to test the question “which soil type results in the highest yield of tomatoes: clay soil or sandy soil? ” measure the growth of 10 tomato plants that are grown in clay soil, and compare it to the growth of 10 tomato plants that are grown in sandy soil. measure the growth of a tomato plant that is grown in clay soil, and compare it to the growth of a tomato plant that is grown in sandy soil. count the number of tomatoes that are produced by a tomato plant that is grown in clay soil, and compare it to the number of tomatoes that are produced by a tomato plant that is grown in sandy soil. compare the average number of tomatoes that are produced by 10 tomato plants that are grown in clay soil to the average number of tomatoes that are produced by 10 tomato plants that are grown in sandy soil.

The last experimental design is the best of the options: 'Compare the average number of tomatoes that are produced by 10 tomato plants that are grown in clay soil to the average number of tomatoes that are produced by 10 tomato plants that are grown in sandy soil''.

The first two experimental designs measure the growth of tomato plants, which is not necessarily related to the yield of tomatoes. The third experimental design compares the tomato yield of the two soils with only one plant grown in each soil. Obviously, the result obtained from this experiment would be statistically weak. The last experimental design compares tomato yield and also uses a larger number of plants in each soil type, so the results obtained would be of slightly greater statistical significance.  

THE ANSWER IS D, JUST TOOK THE TEST PICK
