Answer #1

Ans:

Given that

n=3000 and p=0.001

Approximate to Poisson distribution:

lambda=np=3000*0.001=3

p(m)=(m,3,false)

m p(m)
0 0.050
1 0.149
2 0.224
3 0.224
4 0.168
5 0.101

mean for above data=0*0.050+1*0.149+2*0.224+3*0.224+4*0.168+5*0.101

=2.45

0.250 0.224 0.224 0.200 0.168 0.149 0.150 0.101 0.100 0.050 0.050 0.000 4
