sub questions 4 and 5 please

Transcribed Image Text:Let N be the number of insurance claims per year, and N is following a Poisson distribution, with a rate of
A = 10000 year. We are interested in the probability that the number of insurance claims per year is larger
than 10200.
1. Write down the equation to calculate the probability P(N > 10200).
2. Explain with it is undesirable to calculate this without software or approximations.
3. Use R to calculated P(N> 10200).
4. Write the equation of the normal approximation of this Poisson distribution and calculate P(N > 10200).
You may use R. to calculate cdf or pdf for the Normal distribution.
5. Comment on the approximation of the Poisson-distribution with a Normal-distribution.
