The expected value is what kind of aspect of how probability distribution is characterized?
Expected value is the outcome of confidence of how probability distribution is characterized. If the expected value is greater than the confidence interval then the results are significant.
Can the binomial distribution be normalized?
No. I am using "normalization" as used in probability theory as application of a normalizing constant to a value, to make it conform to a certain distribution.
Can the expected value of a discrete probability distribution be negative?
Yes it can be negative.
What does the mean have to do with a normal distribution?
Almost all statistical distribution have a mean. It is the expected value of the random variable which is distributed according to that function.
Another name for the mean of a probability distribution is its expected value true or false?
Yes, it is true.
Consider a binomial distribution with 10 trials What is the expected value of this distribution if the probability of success on a single trial is 0.5?

What does the expected value of a binomial distribution with n trials tell you?
average number of successes
What is the mean of a normal distribution?

What is the meaning of expected value in a probability distribution?
The expected value is the average of a probability distribution. It is the value that can be expected to occur on the average, in the long run.
What is 9 x 9?
It is a binomial expression.
The expected value is what kind of aspect of how probability distribution is characterized?
Expected value is the outcome of confidence of how probability distribution is characterized. If the expected value is greater than the confidence interval then the results are significant.
What is the expected value of the standard normal distribution equal to?
The expected value of the standard normal distribution is equal to the total amount of the value. It is usually equal to it when the value works out to be the same.
Can the binomial distribution be normalized?
No. I am using "normalization" as used in probability theory as application of a normalizing constant to a value, to make it conform to a certain distribution.
What is 5n minus 20?
(5n - 20) It's a binomial expression in 'n'. Its numerical value depends on the numerical value of 'n'.
What is the expected value of this distribution if the probability of success on a single trail is 0.5?
This is the answer.
The mean or expected value of the distribution of a discrete random variable is?
30.47
Can the expected value of a discrete probability distribution be negative?
Yes it can be negative.
