You can find it by integrating twice:
Given that
, you have
and given
,
8, 14, 12, 17, 4, 6, 2
Mean = average = (8+ 14 + 12 + 17 + 4 + 6 + 2) / 63 = 63/7 = 9
Answer
Mean = 9
Answer:
11.8 ;
0.1036360
Step-by-step explanation:
Mean births per day, μ = number of births per year / number of days in a year ;
4310 / 365 = 11. 8 births per day
From poisson distribution :
P(x) = (μ^x * e^-μ) ÷ x!
P(x = 13) = (11.8^13 * e^-11.8) ÷ 13!
P(x = 13) = 6.453438E8 / 13!
P(x = 13) = 0.1036360
