Answer 2

Answer:

$\huge\bigstar\underbrace{\mathtt\red{A} \mathtt\purple{N} \mathtt\green{S}\mathtt\blue{W} \mathtt\blue{E} \mathtt\orange{R}}\bigstar✌$

Step-by-step explanation:

Mean of 100 observation =50

∴Total of 100 observation=100×50=5000

If one of the observation 50 is replaced by 150 than total of new observation is

=5000−50+150=5100

Hence the mean of new 100 observation=

$\frac{5100}{100}$

=51
