What is sample distribution?
Theoretically, it is the distribution of a statistic based on all possible samples of a given size. In practice, it may be the distribution under repeated samples.
Does an accountant job fall under applied math or pure math?
It is applied math. Math is the purest form there is. psychology is applied biology, which is applied chemistry, which is applied physics, which is applied math, which is pure PURE
What is the area under a discrete probability distribution function?
1.
What is the area under the standard normal distribution called?
One.
How do you find the area of a normal distribution?
The area under a normal distribution is one since, by definition, the sum of any series of probabilities is one and, therefore, the integral (or area under the curve) of any probability distribution from negative infinity to infinity is one. However, if you take an interval of a normal distribution, its area can be anywhere between 0 and 1.
What are the conditions under which you can expect to be able to use a binomial distribution to model a probability distribution?
Two independent outcomes with constant probabilities.
Does the probability of failure vary from trial to trial under binomial distribution?
No. It must remain the same.
How does the probability theory apply to statistics?
Statistics is the study of how probable an observed event is under a set of assumptions about the underlying probability distribution.
What is the probability that exactly 2 have some kind of defect?
The probability is determined by the binomial distribution. We consider p = probability of defect, q = probability of not defect, n = sample size, and x= number of defects in sample, in this case x=2. We calculate the probability as P(X = x) = n!/[(n-x)! x!] pxqn-x If sample size = 10 and p = 0.1 then: P(x= 2) = 10!/(8!x2!)(0.1)2(0.9)8 = 0.1937 You can find more about the binomial distribution under Wikipedia. It is important also to note the assumptions when using this distribution. It must be a random sample and the probability of defects is known.
State a condition under which the binomial distribution can be approximated by poisson distribution?
Because "n" is very large and "p" is very small. where "n'' indicates the fixed number of item. And ''p'' indicates the fixed number of probability from trial to trial.
Where is the PDC located on a 1999 300m?
The power distribution center is the fuse box under the hood.The power distribution center is the fuse box under the hood.
The total area under a normal distribution is infinite?
The total area under a normal distribution is not infinite. The total area under a normal distribution is a continuous value between any 2 given values. The function of a normal distribution is actually defined such that it must have a fixed value. For the "standard normal distribution" where μ=0 and σ=1, the area under the curve is equal to 1.
The normal curve is a symetrical curve named after whom?
Gauss. See his biography. He did not develop it. One link credits Euler for the derivation, yet another link credits de Moivre who derived the normal function as an approximation of the binomial under certain conditions. Galt (1889) termed it the normal distribution.
The distribution of sample means is not always a normal distribution Under what circumstances will the distribution of sample means not be normal?
The distribution of sample means will not be normal if the number of samples does not reach 30.

Where is the power distribution center on a 2001 Dodge Dakota?
The under hood fuse box is the power distribution center.
