Question
Janette is growing tomato seedlings. She just took measurements of her seedlings, and here are her data, in centimeters.

4, 3.5, 6, 7.2, 5, 6.1, 3.6, 7.1, 3, 3.2

What are the mean and median seedling heights?

(1 point)
Mean=
cm. Median=
cm.

Answer 1

[AI-generated answer — Bot GPT 3.5]

To find the mean, we add up all the values and divide by the total number of values:

Mean = (4 + 3.5 + 6 + 7.2 + 5 + 6.1 + 3.6 + 7.1 + 3 + 3.2) / 10
Mean = 48.7 / 10
Mean = 4.87 cm

To find the median, we first need to arrange the values in ascending order:

3, 3.2, 3.5, 3.6, 4, 5, 6, 6.1, 7.1, 7.2

Since there are 10 values, the median will be the average of the 5th and 6th values:

Median = (4 + 5)/2
Median = 4.5 cm

Therefore, the mean seedling height is 4.87 cm and the median seedling height is 4.5 cm.
