An average of 6.3 robberies occur per day in a large city. Find the probability that during a given week there is exactly one day on which exactly three robberies occur.
Use a poisson distribution model, If there are 1653 robberies in a city in a year: What is the probability that in any given day there will be 4 robberies? There will be 3-5 robberies in any day?
1. find the probability 2. what is the mean of robberies occur on a given day, u. 3. what is the standard deviation you found in the last problem? A police department reports that the probabilities that 0, 1, 2, and 3 burglaries will be reported in a given day are 0.48, 0.35,0.13, and 0.04, respectively. ܢܙ x|P(X = x) 0 .48 .35 2 .13 3 .04
A city with 6 districts has 6 robberies in a particular week. Assume the robberies are located randomly, with all possibilities for which robbery occurred where equally likely What is the probability that some district had more than 1 robbery? 23.
Robberies are reported to the police at random times that follow a poisson process with λ = .6 per day. What is the probability that, next week, four robberies are reported, but none are reported on Monday and Tuesday.
The number of murders and robberies per 100,000 population for a random selection of states are shown. Let the x variable be murders and the y variable be robberies. Given that r = 0.8042, Sx = 1.789, Sy = 56.337. Murders 2.4 2.7 5.6 2.6 2.1 3.3 6.6 5.7 Robberies 25.3 14.3 151.6 91.1 80 49 173 95.8 a) Find the equation for the regression line. b) Find the predicted value for the number of robberies when x = 4.
C1: Snow Manufacturing Co. has 6 machines that perform a particular task. Breakdowns occur frequently for this machine. Past records indicate that the number of breakdowns that occur each day is described by the following probability distribution: SK2: 5 marks Number of Probability Breakdowns 0.2 0.3 0.4 More than 3 0.0 Required: 1. What is the expected number of breakdowns in any given day? (2 marks) 2. What is the variance for this distribution? (1 mark) 3. What is the...
