- Suppose that the time students wait for a bus can be described by a uniform random variable X, where X is between 15 minutes and 55 minutes. (a) What is the probability, P that a student will wait between 15 and 25 minutes for the next bus?P = (b) What is the probability, P that a student will have to wait at least 25 minutes for the next bus?arrow_forwardIt is known that 51% of American college students fail a course during their freshman year. A university journal club randomly samples 9 upperclassmen and asks them if they failed a course during their freshman year, 3 say they have. Suppose a hypothesis test is to be conducted to determine if the proportion of students who failed a course during their freshman year is less than 0.51. The random variable is X = the number of students in the sample that failed a course during their freshman year. What values of X are considered "as or more unusual" than the observed count if the null hypothesis is true? X ≥ 3 3 ≤ X ≤ 4.59 X ≥ 4.59 X ≤ 4.59 X ≤ 3arrow_forwardIt is said that the number of traffic accidents in Sinchon Rotary follows the Poisson distribution, of which the expected value is three times per hour. When the number of traffic accidents in the Sinchon Rotary during the 30 days independent of each other is X1, X2, ..., X30, answer the following questions. (1) The random variable Y is the sum of the number of traffic accidents in the Sinchon Rotary for 30 days independent of each other. Find the distribution of Y. (e.g. normal distribution, binomial distribution, etc.) (2) Use (1) to calculate the probability that the time until two traffic accidents occur in 30 days exceeds 20 hours. (3) For three years, Mike had never seen a traffic accident while traveling the Sinchon Rotary almost every day, so he usually thought that the number of traffic accidents would be less than three per hour. To confirm this, A surveyed the number of traffic accidents at Sinchon Rotary for one hour for 30 days, and as a result, the average number of…arrow_forward
- a manufactoring company produces 10,000 platics cups per day. This company supplies cups to a supermakret which sells them in packs of 10 per pack. Ig less than two of a ranfdomlu slected pack (of 10 cups) from the order are defective, the supermarket accepts the whole order. The proportion of defective cups produced by the manufactoring company is 10%. Let X be the random variable representing the number of defective cups in a pack. i) identify the type of distribution being described in this question and write down the value of its parameters. ii) what is the probability that the order will be accepted? iii) What is the probability that a randomly selected pack (of 10 cups) has more than two defective cups?arrow_forwardSuppose that40%of the applicants for a certain job possess advanced training in computerprogramming.

They have 79 employees and each employee has a 67% chance of drinking coffee in the break room each day. Recall, for a binomial random variable, dbinom(j,n,p) P(Y = j) and pbinom(j,n,p) = P(Y < j).

There are two dedicated technicians that are capable of repairing the snowmobiles. A broken down snowmobile will be repaired by one of these technicians (when one becomes available) and the repair time of a snowmobile can be modeled as an exponential random variable with a mean of .4 weeks. (a) Describe a queueing system model of the repair operations of the snowmobiles by answering the following questions: What are the customers in the queueing system? What are the servers and what service is being provided? b) Provide the rate transition diagram of the birth and death process that captures the queueing system.
