The mean height of the plants without the use of the fertilizer is
27.0 cm.
Given the heights of plants with no usage of fertilizer:
24.1 cm, 25.9 cm, 25.4 cm, 24.1 cm , 35.6 cm
and the heights of plants with the effect of fertilizer:
30.5 cm , 32.1 cm, 40.6 cm, 30.5 cm, 33.8 cm
we are asked to find the mean height of the plants with no usage of fertilizers.
In mathematics and statistics, the mean is the average of a group of variables. There are several ways to calculate the mean, such as the geometric mean and the harmonic mean. The simple arithmetic mean involves adding the numbers together and dividing the result by the number of observations.
mean = adding all numbers together and dividing by the number of items in the list.
mean = 24.1 ₊ 25.9 ₊ 25.4 ₊ 24.1 ₊ 35.6 / 5
mean = 135.1 / 5
mean = 27.0 cm
Hence we get the mean height of the plants with no usage of fertilizer is 27.0 cm.
