Helen recorded the number of tomatoes on each of her tomato plants and then arranged the numbers from smallest to largest. the number of tomatoes on each plant were 5, 5, 5, 6, 9, 10, 10,10, 10, and 10. the mean number of tomatoes was 8. what is the mean absolute deviation? 0.0 2.0 2.2 4.4

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.
