1.	In a Poisson distribution if standard deviation is 3, the find the mean.
Answer» Given S.D = √variance = 3 Squaring on both sides variance = 9 In Poisson distribution mean = variance ∴ mean = 9.

In a Poisson distribution if standard deviation is 3, the find the mean.

Answer»

Given S.D

= √variance = 3

Squaring on both sides

variance = 9

In Poisson distribution mean = variance

∴ mean = 9.
