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

How many people would you need to get together to have two people with a birthday in the same month?
To be certain of it, you would need twelve people (simply because that is the number of different possibilities).
To have a better than even chance of it, you would need at least 5 people.
And the correct answer will of course be - 13
If you have 12, they might all have birthdays in different months.
A better than even chance will have to be more than 6 and therefore that answer would be 7.
Refer back to the first clause. The answer is 50 per cent!
What is 19 over 7 as a percentage?
Expressed as a percentage, 19/7 x 100 = 271.428571 recurring (that is, 271.428571428571...) percent.
Inverse Gaussian distribution-discuss moment and maximum likelyhood estimation?
I've included two links. The MLE of parameters of NIG distribution is the subject of current research as attached. The moment generating function is provided in the first link.
If a zero is placed behind a number is it even or odd?
Placing a zero to the right of a number multiplies it by a factor of 10, and all multiples of 10 are even numbers.
(10 = 2 x 5).
A sum that is a factor of 6 has a greater probability.to my dick
The median.
How many times will a roulette wheel will stop on 0 if spun 190 times?
There are two different kinds of roulette wheels: those with numbers 1-36, 0 and 00 and ones without the 00. The first one will be expected to stop on zero 5 times, the second 5.14 times.
How many numbers start from 1000 up to 9999 which all the digits in all places are even numbers?
4*5*5*5 = 500
How do you get a random number generator on Microsoft Excel?
"=rand()" in a cell gives a random number between 0 and 1. Every time the sheet is recalculated (F9 key) a new random number is generated.
What are the chances of rolling the dice at 1?
For a six sided die , it would be 1/6 as there is an equal chance for every value.
Why logarithmic function is used to represent information?
I believe that Logarithmic functions are used to represent information because they are calculated and people take the time to actually put effort into finding an answer, and graphing it.
What is the formula for the deviation?
Standard deviation is a way to describe how the data is distributed around the Arithmatic Mean. It is not a simple formula to calculate, as shown in the links.
How many positive numbers have a ones digit of 2?
There are infinitely many such - every tenth number after 2 ends in 2.

96425
Larger numbers can be made by cascading the powers, but not on here because the notation won't take it.
What is the point where the line of long meet called?
The lines of longitude meet at the north and south poles.
No.
What kind sampling based on probability?
Probability sampling, according to which, a member of the population has the same probability of being included in the sample as any other member. Equivalently, each sample of a given size has the same probability of being chosen.
Stratified and cluster sampling are variations on this idea. In stratified sampling, the population can be divided up into strata such that members within each stratum are more like each other than across strata. One example may be school pupils in different year groups. A sampling scheme could assign a number to be sampled from each stratum (perhaps according to how large that group is) and then, within that stratum, to use simple probability sampling.
Cluster sampling is used when the entire population can be split up into clusters. Clusters are selected using probability sampling. Then a census is used within each cluster. For example, if you wanted to sample schools across the country, a simple probability sample would result in schools all over the country and the travelling costs (and time) would be prohibitive. Instead, you divide the country up into regions and take a probability sample of these regions. You end up visiting every school within the few selected regions.
