What is the number of trials in a binomial distribution that has a mean of 8 and a standard deviation of 2?

There are 16 trials. Full Answer

Is binomial distribution is characterized by situations that are analogous to coin tossing?

Yes it is. For a binomial, there must be a fixed number of trials, the probability must remain constant for trials, trials must be independent, and each outcome must be classified into 2 categories. Full Answer

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?

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? Full Answer

What does the expected value of a binomial distribution with n trials tell you?

average number of successes Full Answer

Can a binomial experiment be used to find the probability of 4 outcomes of .20 and 16?

If the question is about 4 successful outcomes out of 16 trials, when the probability of success in any single trial is 0.20 and independent of the outcomes of other trials, then the answer is, yes, the binomial experiment can… Full Answer

What is she binomial probability distribution is used with?

It is used when repeated trials are carried out , in which there are only two outcomes (success and failure) and the probability of success is a constant and is independent of the outcomes in other trials. Full Answer

What is required in a binomial distribution?

A number of trials, each of which has only two outcomes: these are usually termed "success" and "failure". The trials must be independent and the probability of success must remain constant. Full Answer

What is the parameters that determine a Binomial Distribution?

The binomial distribution has two parameter, denoted by n and p. n is the number of trials. p is the constant probability of "success" at each trial. Full Answer

How can you approximate a binomial distribution to a poison distribution when the number of binomial trials became large enough?

The Poisson distribution with parameter np will be a good approximation for the binomial distribution with parameters n and p when n is large and p is small. For more details See related link below Full Answer

How do you differentiate a Poisson distribution and a binomial one in a level qns?

The Poisson distribution is characterised by a rate (over time or space) of an event occurring. In a binomial distribution the probability is that of a single event (outcome) occurring in a repeated set of trials. Full Answer

Is the possible values for a binomial random variable the whole numbers from zero to infinity?

No. A binary distribution gives the probability of obtaining x successes in n trials, x can not be greater than n. The binomial distribution can be used for any whole number greater than 0, but the distribution is not unbounded… Full Answer

What are the requirements for the binomial probability distribution?

The requirements are that there are repeated trials of the same experiment, that each trial is independent and that the probability of success remains the same. Full Answer

When can a binomial situation be approxiamted with a normal distribution?

The binomial distribution can be approximated with a normal distribution when np > 5 and np(1-p) > 5 where p is the proportion (probability) of success of an event and n is the total number of independent trials. Full Answer

What is the Assumptions for a Binomial distribution and Poisson?

For the binomial, it is independent trials and a constant probability of success in each trial. For the Poisson, it is that the probability of an event occurring in an interval (time or space) being constant and independent. Full Answer

What is the important law of binomial distribution?

1 - 2 answers 2 - probabilty of success remains constant 3 - outcomes of trials are independent 4 - random variable of interest is the number of successes in a fixed number of of trials Full Answer

What does the random variable (r) for a binomial experiment of n trials represent?

It can represent anything you want it to. The conventional use is that it represents the number of successes. Full Answer

How you can use negative binomial distribution in everyday life?

The negative binomial can be applied in any situation in which there is a series of independent trials, each of which can result in either of just two outcomes. The distribution applies to the number of trials that occur before… Full Answer

Why do you use binomials?

Binomials are used when the total of n independent trials take place and one wants to find the probability of r successes, when each success has a probability "p" of occurring. There should be independent trails, Probability of success stays… Full Answer

Is rolling a single loaded die 58 times keeping track of the numbers tat are rolled binomial distrubition?

No. A binomial distribution consists of trials with only two possible outcomes. The experiment described in the question has six - unless the die is so seriously loaded that only two outcomes are possible. Full Answer

Does a binominal distribution with trials that are independent mean that the outcome of one trial does not affect the outcome of any other trial?

No. The fact that the outcome of one trial does not affect the outcome of any other trial follows from the fact that the trials that are independent. Whether the distribution is binomial or not is totally irrelevant. Full Answer

What is so negative about negative binomial distribution?

Nothing really. It concerns an experiment with identified success and failure probabilities (p and q), or Bernoulli trials, like the conventional binomial distribution. In an negative binomial experiment, the experiment is stopped after "r" successes occur in n trials. Thus… Full Answer

Which expression is used to find the expected value of X in binomial distribution?

If X takes the value 1 with probability p and 0 with probability (1-p), and there are n independent trials then E(X) = np Full Answer

What is the relationship between the binomial expansion and binomial distribution?

First i will explain the binomial expansion Full Answer

How do you do binomial distribution?

You distribute the binomial. Full Answer

What is a binomial times a binomial?

You have to multiply each term in the first binomial, by each term in the second binomial, and add the results. The final result is usually a trinomial. Full Answer

What is a binomial coefficient?

A binomial coefficient is a coefficient of any of the terms in the expansion of the binomial (x+y)^n. Full Answer

What is a binominal theorem?

The binomial theorem describes the algebraic expansion of powers of a binomial, hence it is referred to as binomial expansion. Full Answer
