In the accounting department of a bank 100 accounts are selected at random and examined for errors. Suppose the following results have been obtained : No. of errors 1 2 3 6. No. of accounts : 35 40 19 2 2 2 On the başis of this information can it be concluded that the errors are distributed according to the poisson probability law ?

2. If electricity power failures occur according to a Poisson distribution with an average of 5 failures every 20 weeks, calculate the probability that there will not be more than one failure during a particular week.

Can I get help for question B?

Chu (2003) studied the number of goals scored during the 232 World Cup soccer games played from 1990 to 2002 and found them to be well modeled by the Poisson distribution. Only goals scored during the 90 minutes of regulation play were considered. The average number of goals scored each game was 2.5. Assuming that this mean continues to hold for other World Cup games, find the probabilities associated with the following events. a. At least six goals are scored during the 90 minutes of regulation play in a randomly selected game during the nextWorld Cup. b. No goals are scored during the 90 minutes of regulations play in a randomly selected game during the nextWorld Cup. c) Plot the probability distribution with n=10.
