Question

use a calculator to compute the average heights of the plants in each group to the nearest centimeter week 1 average height control group cm exper group cm done

Explanation:

To solve for the average heights, we first need to determine the heights of each plant in the Control Group and Experimental Group from the image (assuming the ruler is in cm and we can estimate the heights):

Control Group (Plants 3, 4, 5, 6)

• Let's assume the heights (from the ruler) are: Plant 3: 10 cm, Plant 4: 15 cm, Plant 5: 20 cm, Plant 6: 15 cm (estimating from the image)

Step 1: Calculate the sum of Control Group heights

Sum = \( 10 + 15 + 20 + 15 \) = \( 60 \) cm

Step 2: Calculate the average of Control Group

Average = \( \frac{\text{Sum}}{\text{Number of plants}} = \frac{60}{4} = 15 \) cm

Experimental Group (Plants 1, 2, 3, 4, 5, 6)

• Let's assume the heights (from the ruler) are: Plant 1: 5 cm, Plant 2: 10 cm, Plant 3: 15 cm, Plant 4: 20 cm, Plant 5: 25 cm, Plant 6: 30 cm (estimating from the image)

Step 1: Calculate the sum of Experimental Group heights

Sum = \( 5 + 10 + 15 + 20 + 25 + 30 \) = \( 105 \) cm

Step 2: Calculate the average of Experimental Group

Average = \( \frac{\text{Sum}}{\text{Number of plants}} = \frac{105}{6} \approx 17.5 \approx 18 \) cm (rounded to nearest cm)

Final Answers:

• Control Group Average Height: \( \boldsymbol{15} \) cm
• Experimental Group Average Height: \( \boldsymbol{18} \) cm (Note: These values are based on estimated heights from the image. If the actual heights differ, recalculate with the correct measurements.)
