Statistics
Statistics deals with collecting, organizing, and interpreting numerical data. An important aspect of statistics is the analysis of population characteristics inferred from sampling.

The probability of this kind of event is 0?
If the probability is 0, the event has no chance of happening.
How do you get two sixs on dice?
Just try again and again. On average, you should get two sixes, once every 36 tries.

How many decimeters are there in 800 meters?
There are 10 decimetres in one metre. Therefore, 800 metres is equal to 800 x 10 = 800 metres.

Type of graph is best suited for finding a trend between two sets of non-continuous data?
scatter plot
When do you use a z-value rejection region when testing a claim about a population mean?
If you know the population variance or if you have a very large sample then you could reliably use a Z test. Otherwise you should use a t test and use s^2 as an estimator for the population variance.

Can carbon ages can be used as independent or dependent variable?
Either.
You could have carbon isotope ratios as your independent and carbon age as your dependent.
or
You could have the carbon age of soil samples as your independent and the artefacts that you are trying to date as the dependent.
The answer would be 7x7x7x7. 2401 to 1.

The probability is the area under the normal curve between -∞ and the z-value corresponding to 11:00 for a mean of 9:45 and a standard deviation of 65 minutes. When using single tailed tables, they give the area between the mean and the z-value, ranging from 0 to 0.5. So to find the area between -∞ and the z-value it is the value form the single-tailed table of the z value plus 0.5
For working with time, it will be easier to work in minutes.
9:45 to 11:00 is 1 hr 15 minutes = 75 minutes = x - µ
z = (x - µ)/standard deviation
= 75/65 ≈ 1.154
→ area using single-tailed tables is approx 0.3758
→ probability ≈ 0.5 + 0.3757 = 0.8757 or approx 87.6%
When two peoples meet eyes become four but why two heart meet become one?
Not really. The first clause is a physical observation, the second is a metaphor.
How do you select random numbers in simulation problem?
Most computers will have a function that will generate [pseudo] random numbers.
The precise way such numbers are generated is language-dependent and dependent on the library used with that language. For instance, if you were writing simulation code in the Python language using the scipy library then you could obtain five pseudorandom Poisson values in an array from a distribution with parameter 1.2 with the following code.
from scipy.stats import poisson
poisson ( 1.2 ) . rvs ( 5 )
