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

Explanation of if you give everyone a slice of your pie you will still have more than enough?
it means u have enough pie to give everyone a second piece.
Could a data set ever have the same meanmedianmode and a range of 0?
You'd have to have a number of the same number like three threes or four fours, etc.
What ten numbers have a median of 5 a mode of 3 a range of 9 and mean of 5?
(1, 3, 3, 3, 5, 5, 6, 6, 8, 10)
What do you mean by percentage points?
It just means percentage, but usually rounded to whole numbers.
88.3% becomes 88 percentage points
What is the probability that at least one tail appears when tossed 6 times?
you have 63 chances out of 64. i once witnessed a coin being tossed seven times and giving up 7 consecutive heads. we never tried it an eighth time, 7 heads and you had to go to the bar.
What percent probability is associated with a z-value of 1.3?
None.
The probability of a continuous variable taking any particular value is always zero. The probability is greater than zero only when an interval (or range) is specified.
How do you get to one when you add on third plus one sixth plus one sixth?
(1) - (1/3 + 1/6 + 1/6) =
(1) - (2/6 + 1/6 + 1/6) =
(1) - (4/6) =
(6/6) - (4/6) =
(2/6) =
1/3
What is the probability of failing 75 times on a 2 percent chance of success?
If the probability of succeeding is 2%, then the probability of failing is 98%. The probability, then, of failing 75 times is 98%75, which is 22%.
What is the difference between natural infinite numbers and real infinite numbers?
A natural number is a counting number, such as 1, 2, 3. There are also known as whole numbers and integers. They can be infinitely large.
A real number is a number, possibly a natural number, but more possibly not, because there are an infinite number of real numbers that lie between any two natural numbers, such as 1, 1.1, 1.11, 1.111, 111112, etc, ad infinitum. Real numbers can also be infinitely large.
Yes. We know the distance from the Earth to the Moon very precisely, on the order of millimeters or less. The Apollo astronauts left "corner reflectors" on the Moon's surface, and when we fire a laser pulse at it, we can detect the precise moment when the reflection gets back to our sensor. Because we know the speed of light VERY precisely, we can calculate the distance based on the time from when the pulse is fired to when the reflection is returned.
We can calculate the distances to other space probes the same way - we send a radio signal, wait for the reply, and calculate the distance.
Can validation rules make sure that a users entry falls within a range of values?
Yes, but it depends on the validation routines used.
How May 7 digit number are there when 0 and 2 cannot be the leading number?
8*10*10*10*10*10*10 = 8*106 or 8 million.
What 5 numbers have a range of 8 and a median of 6?
can start by finding the minimum and maximum values. Since the range is 8, the minimum value must be 6 - (8/2) = 2 and the maximum value must be 6 + (8/2) = 10.
Now we need to find 5 numbers between 2 and 10 that have a median of 6. Since there are an odd number of values, the median will be the middle value when the numbers are sorted in ascending order. Therefore, we can choose any two numbers less than 6 and two numbers greater than 6, and then include 6 as the middle value.
For example, we could choose the following five numbers: 2, 4, 6, 8, 10. The range of these numbers is indeed 8, and their median is also 6.
Therefore, one possible set of five numbers with a range of 8 and a median of 6 is 2, 4, 6, 8, and 10.
