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.

What is the Test for normal distribution?
Normal Distribution is a key to Statistics. It is a limiting case of Binomial and Poisson distribution also. Central limit theorem converts random variable to normal random variable. Also central limit theorem tells us whether data items from a sample space lies in an interval at 1%, 5%, 10% siginificane level.
What type of graph can be used to display the distribution of a nominal level variable?
It is a bar chart.
Define p-value vs - z score?
The p-value is the probability of any event or the level of significance for any statistical test. The z-score is a transformation applied to a Random Variable with any Normal distribution to the Standard Normal distribution.
What role does the Central Limit Theorem play in evaluation of the confidence level or hypothesis testing?
Without getting into the mathematical details, the Central Limit Theorem states that if you take a lot of samples from a certain probability distribution, the distribution of their sum (and therefore their mean) will be approximately normal, even if the original distribution was not normal. Furthermore, it gives you the standard deviation of the mean distribution: it's σn1/2. When testing a statistical hypothesis or calculating a confidence interval, we generally take the mean of a certain number of samples from a population, and assume that this mean is a value from a normal distribution. The Central Limit Theorem tells us that this assumption is approximately correct, for large samples, and tells us the standard deviation to use.
What is the standard normal distribution for the area to the left of z-1.72 and show work?
Area to the left of z = -1.72 = area to the right of z = 1.72 That is ALL the "working" that you will be able to show - unless you are into some serious high level mathematics. Most school teachers and many university lecturers will not be able to integrate the standard normal distribution: they will look it up in tables. (I have an MSc in Mathematical Statistics and I could do it but not without difficulty). Pr(z < -1.72) = 0.042716

How do you use binomial probability to assess if an outbreak of an illness has occurred or not?
If the illness is infectious then you cannot use the binomial distribution because the incidences of illness are no longer independent events, so that the assumptions required for the binomial distribution are not satisfied. Suppose the illness is not infectious and the "normal" rate of illnesses is p. Then in a group of size n, the number of units suffering has a B(n, p) distribution. You can then determine a critical region at an appropriate level of significance and test the number of victims against that.
Compare binomial array with chebyshev array?
chebyshev has less side lobe level compared to binomial arrays
What is the product of a binomial and its conjugate pair called as in vocabulary?
The answer depends on the level of mathematics. With complex numbers, it is the squared magnitude of the binomial.
Which table do you have to look at to find the level of significance- i.e alpha equals .05 when testing a hypothesis?
The answer depends on what the underlying probability distribution function is. Most statistical textbooks will contain tables for the binomial, Poisson, Standard Normal, Student's t, Fisher's F, Chi-squared, Pearson's r tests. Then there are lots of non-parametric tests (Spearman's Rank, Mann Whitney U, Kolmogorov-Smirnoff for example) for which there are other tables but these are less widely published. And lastly, there are tests for even more esoteric distributions.
What is the Zero Level Distribution Channel?
There can be a number of different levels to each distribution channel. There is the zero level channel, which involves distribution with no intermediaries whatsoever. For smaller markets, using a zero or one level scheme can be quite practical and effective. By Tauqueer :)
What is an 0001 probability level?
The answer depends on the underlying distribution.
Why is catalase test not a good differential test?
becouse it can differentiate organisms up to specie level
What distribution channels are used by LUX?
one level channel
What electron distribution is Mn?
The electron distribution differs between energy levels. In this case, levels one and four have 2 electrons, level 2 has eight, and level 3 has thirteen.
How would you measure the level of customer satsfaction as far as physical distribution is concerned?
I would measure the level of the customer satisfaction as far as the physical distribution is concerned based on the feedback that they will provide.
What circumstances would two species share part of a binomial name?
At the genus level. Panthera leo. Panthera tigris.
