The number of messages arriving at a multiplexer is a poisson random variable with mean 15 messages/second. use the central limit theorem to estimate the probability that more than 950 message arrive in one minute.

0.048 is the probability that more than 950 message arrive in one minute.

Step-by-step explanation:

We are given the following information in the question:

The number of messages arriving at a multiplexer is a Poisson random variable with mean 15 messages/second.

Let X be the number of messages arriving at a multiplexer.

Mean = 15

For poison distribution,

Mean = Variance = 15

From central limit theorem, we have:

where n is the sample size.

Here, n = 1 minute = 60 seconds

P(x > 950)

Calculation the value from standard normal z table, we have,  

0.048 is the probability that more than 950 message arrive in one minute.

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.
