Question

Anvi measured the height of five plants over a three-week experimental period and obtained the following data for the final week (in cm): 15, 18, 21, 19, 20 Calculate the final average height for this group of plants. Round your answer to one decimal place. (1 point) Responses 13.3 cm 13.3 cm 6.0 cm 6.0 cm 4.2 cm 4.2 cm 18.6 cm

Answer 1

To calculate the average height, we need to add up all the heights and divide by the total number of plants.

15 + 18 + 21 + 19 + 20 = 93 cm

There are 5 plants, so the average height is 93 cm divided by 5 plants:

93 cm / 5 plants = 18.6 cm

So, the final average height for this group of plants is 18.6 cm.
