Question

Mr. Fowler's science class grew two different varieties of plants as part of anexperiment. When the plant samples were fully grown, the studentscompared their heights.PlantvarietyHeight of plant(inches)20, 17, 19, 18, 21Mean Mean absolute deviation(Inches)Variety A191.2Variety B13, 18, 11,9,14132.4Based on these data, which statement is true?O A. The maximum height for plants from variety B is greater than forvariety A.B. Plants from variety A always grow taller than plants from variety B.C. The height of a plant from variety B is likely to be closer to themean.D. The height of a plant from variety A is likely to be closer to themean.

Answer 1

Let's analyze all the statements and see why they are false or true.

A. FALSE

The tallest plant in variety B is just 18 tall, while the variety A we have 21.

B. FALSE

We do have plants in A that have the same height as B.

C. FALSE

The standard deviation measure how far it's from the mean, the variety B has a 2.4 standard deviation, which means that the height can be more distant from the mean than in variety A.

D. True

Justified by C. Variety A has a 1.2 standard deviation, which means it's more likely to be closer to the mean
