The first error Emi made in computing the variance is failing to find the difference of 89 - 78 correctly.
<h3>What is Mean?</h3>
This is defined as the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.
In this case , sum of given numbers = 87+46+90+78+89 = 390

Answer:
D
Step-by-step explanation:
We observe that the values of m are 10 less than the corresponding values of n, that is
n = 10 → m = 10 - 10 = 0
n = 12 → m = 12 - 10 = 2
n = 15 → m = 15 - 10 = 5
n = 19 → m = 19 - 10 = 9
In general
m = n - 10 → D
