Question

Arithmetic mean of 10 observation was found to be 22. If one more observation 44 was to be added to the data ,what would be the new mean.

Answer 1

Step-by-step explanation:

sum of number=22×10=220

now new sum=220+44=264

mean=264/11=24

Answer 2

Answer:

24

Step-by-step explanation:

Let the mean be given by :-

$\frac{a1+a2+...+a10}{10}=22$

$a1+a2+...+a10=220$

Let the new mean be $x$ given by:-

$x=\frac{a1+...a10+44}{11}=\frac{220+44}{11}$

$x=24$
