About 3.6 babies are born each day at a local hospital. Assuming the Poisson distribution, what is the probability that no babies are born today?
Round to 4 decimal places.
In a local hospital ,3.6 babies are born each day.
X: Number of babies born in a day.
The probability mass function of Poisson distribution is
Now , the probability that no babies are born today is

1. About 2.9 babies are born each day at a local hospital. Assuming the Poisson distribution, what is the probability that no babies are born today? Make sure your answer is between 0 and 1. 2. A travelling salesman sells milkshake mixing machines and on average sells 7.1 machines per month. He needs to sell at least 3 machines each month order to stay in business, otherwise he will shut down. What is the probability he will have to shut...
Assume the number of births in a local hospital follows a Poisson distribution and averages 2.6 per day. Complete parts a through c. a. What is the probability that no births will occur today? The probability that no births will occur today is 0.0743 . (Round to four decimal places as needed.) b. What is the probability that fewer than five births will occur today? 1. The probability that fewer than five births will occur today is (Round to four...
We considered a town with two hospitals. In the large hospital about 45 babies are born each day, and in the smaller hospital about 15 babies are born each day. We were interested in guessing which hospital would have on the average the largest number of days with the property that more than 60 percent of the children born on that day are boys. The probability of a boy being born is 0.5 For each hospital find the expected number...
Suppose that 55% of all babies born in a particular hospital are boys. If 7 babies born in the hospital are randomly selected, what is the probability that at least 3 of them are boys? Carry your intermediate computations to at least four decimal places, and round your answer to two decimal places.
Suppose that 50% of all babies born in a particular hospital are girls. If 6 babies born in the hospital are randomly selected, what is the probability that more than 1 of them are girls? Carry your intermediate computations to at least four decimal places, and round your answer to two decimal places.
4. At a local hospital, babies are born at an average rate of four births per night (consider "night" to be an 8 hour period from 10pm to 6am). Assume that the time that elapsed from one birth to the next has the exponential distribution. Take note that we are concerned only with the rate at which babies are born, and we are ignoring the time spent in labor. We must also assume that the times spent between births are...
Question 13 0.2 pts Suppose you are taking a multiple choice exam with 55 questions, each with 4 possible answers. If you were to guess at random for each question, how many questions would you expect to get right? Your answer does not need to be an integer. Question 14 0.2 pts On average 1.8 babies are born each day at a local hospital. Assuming the Poisson distribution, what is the probability that no babies are born today?
Suppose babies born in a large hospital have a mean weight of 3242 grams, and a standard deviation of 446 grams. if 107 babies are sampled at random from the hospital, what is the probability that the mean weight of the sample babies would be less than 3285 grams Round your answer to four decimal places
Suppose babies born in a large hospital have a mean weight of 3366 grams, and a variance of 244,036. If 118 babies are sampled at random from the hospital, what is the probability that the mean weight of the sample babies would differ from the population mean by more than 45 grams? Round your answer to four decimal places.
Suppose the number of babies born during an 8-hour shift at a
hospital's maternity wing follows a Poisson distribution with a
mean of 5 an hour. Find the probability that six babies are born
during a particular 1-hour period in this maternity wing. Round to
six decimal places.
