Question

Using the following data set, what is the mean of the medium soil?

Answer 1

Answer:

Option B, 12

Explanation:

As per the data given in the table (as in the attachment), there are three readings for the water amount in medium soil

Reading 1 - 13

Reading 2- 13

Reading 3- 10

Mean of any observation is equal to the sum of value of all observations divided by the total number of observations.

Thus, here the mean would be

$\frac{13+13+10}{3} \\= 12$

Thus, the correct answer is option B, 12

Answer 2

12 is the average of these numbers
