The computer that controls a bank's automatic teller machine crashes a mean of 0.4 times per day. What is the probability that, in any seven-day week, the computer will crash less than 5 times? Round your answer to four decimal places.
The computer that controls a bank's automatic teller machine crashes a mean of 0.4 times per day. What is the probability that, in any seven-day week, the computer will crash at least 4 times? Round your answer to four decimal places.
my C Cour The times per week a student uses a lab computer are normally distributed, with a mean of 5.9 hours and a standard deviation of 1.4 hours. A student is randomly selected. Find the following probabilities. Anno (a) Find the probability that the student uses a lab computer less than 4 hours per week. (b) Find the probability that the student uses a lab computer between 6 and 8 hours per week. (c) Find the probability that the...
Many of a bank’s customers use its automatic teller machine to transact business after normal banking hours. During the early evening hours in the summer months, customers arrive at a certain location at the rate of one every other minute. This can be modeled using a Poisson distribution. Each customer spends an average of 83 seconds completing his or her transactions. Transaction time is exponentially distributed. a. Determine the average time customers spend at the machine, including waiting in line...
The time between arrivals of customers at an automatic teller machine is an exponential random variable with a mean of 5 minutes. A) What is the probability that more than three customers arrive in 10 minutes? B) What is the probability that the time until the 6th customer arrives is less than 5 minutes?
Arrivals to a bank automated teller machine (ATM) are distributed according to a Poisson distribution with a mean equal to four per 5 minutes. Complete parts a and b below. a. Determine the probability that in a given -minute segment, will arrive at the ATM. The probability is nothing. (Round to four decimal places as needed.) b. What is the probability that fewer than customers will arrive in a -minute segment? The probability is
VULJUURIU The National Australia Bank undertook a study to monitor teller service times for their surburban Perth branches. They found service times could be adequately approximated by a normal distribution with a mean of 137 seconds and a standard deviation of 29 seconds. Determine the probability that a teller in one of these branches completes their next service in less than two minutes (four decimal places).
A soft drink machine outputs a mean of 28ounces per cup. The machine's output is normally distributed with a standard deviation of 3 ounces. What is the probability of putting less than 30 ounces in a cup? Round your answer to four decimal places.
A soft drink machine outputs a mean of 29 ounces per cup. The machine's output is normally distributed with a standard deviation of 3 ounces. What is the probability of putting less than 34 ounces in a cup? Round your answer to four decimal places.
Reaction time is normally distributed, with a mean of 0.6 sec and a standard deviation of 0.1 sec. Find the probability that an individual selected at random has the following reaction times. (Round your answers to four decimal places.) (a) greater than 0.7 sec (b) less than 0.4 sec (c) between 0.4 and 0.7 sec
