What is an example of a problem whose expected value is equal to 5000?
The expected value of the number of Heads in 1 toss of a fair coin is 0.5. So the expected number of Heads in 10000 tosses of a fair coin is ... 5000!
Is the expected value the same as the standard deviation?
No. The expected value is the mean!
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.
Can expected value be negative?
yes
If x squared equals k where x and k are integers What is the value of k?
All we can deduce from that information is that k is a positive perfect square. Is that really the whole question? What?
What is the formula for expected value of perfect information?
Evopi = evw/pi – evw/o pi
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.
How does information get value?
The value of perfect information is a management accounting theory which highlights the difference between the expected value based on probability of occurrence and the maximum possible value a seller or manufacturer can make if he or she has an idea of actual demand for his or her products.
Is the expected value of a discrete random variable equal to the mean of the random variable?
yes?

What is the residual for the point (36)?
A residual is defined in the context of some "expected" value. There is no information in the question regarding expected values.
How do you calculate the expected value when you know the standard deviation?
You cannot; there is insufficient information.
What is the chi square test used for?
The chi-squared test is used to compare the observed results with the expected results. If expected and observed values are equal then chi-squared will be equal to zero. If chi-squared is equal to zero or very small, then the expected and observed values are close. Calculating the chi-squared value allows one to determine if there is a statistical significance between the observed and expected values. The formula for chi-squared is: X^2 = sum((observed - expected)^2 / expected) Using the degrees of freedom, use a table to determine the critical value. If X^2 > critical value, then there is a statistically significant difference between the observed and expected values. If X^2 < critical value, there there is no statistically significant difference between the observed and expected values.
Is the expected value the same as the standard deviation?
No. The expected value is the mean!
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.
How do i find expected value in a martingale system?
The expected value of a Martingale system is the last observed value.
Tell me something about valuation of a bond?
Bond valuation has one fundamental principle. This principle is that the bond has a value that is equal to the present value of the expected cash flow that will occur in the future.
