- Find the mean of first n natural number.
- What is the value of sum of deviations taken from arithmetic mean?​

Answer 1

Answer:

Step-by-step explanation:

We can use the Karl Pearson’s empirical formula Mean-Mode=3(Mean-Median) to derive the median.

Putting the values,

24–18=3×24–3×Median

Or, 6=72–3×Median

Or, 2=24-Median

So, median= 22.
