A multinational company operates factories around the world. Assume that the total number of serious accidents that take place per week follows a Poisson distribution with mean 2. We assume that the accidents occur independently of one another
(a) Calculate the probability that there will be two or fewer accidents during one week.
(b) Calculate the probability that there will be two or fewer accidents in total during a period of 2 weeks.
(c) Calculate the probability that there will be two or fewer accidents each week during a period of 2 weeks.
(d) The company is shut for two weeks for seasonal celebrations and therefore, over a whole year, the number of accidents follows a Poisson distribution with mean 100. Using a suitable approximation, calculate the probability that there will be more than 120 accidents in one year.
Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
