Question

use the table to complete the sentence below.
when the yarrow plants were grown at high altitude instead of at low altitude, the
average height of type 1 plants was cm greater, and the average height of type
plants was cm less.

Explanation:

Step1: Calculate the difference for Type 1

Subtract the low - altitude height from the high - altitude height for Type 1.
$$62.4 - 54.1$$

Step2: Calculate the difference for Type 2

Subtract the high - altitude height from the low - altitude height for Type 2.
$$54.3 - 33.2$$

Answer:

The average height of type 1 plants was \(8.3\) cm greater, and the average height of type 2 plants was \(21.1\) cm less.
