Whew... that makes 18 two-digit numbers that have a "2".
How To get valid results small samples are sufficient?
I will assume the sample is random. In general, the larger the sample, the smaller the percentage error will be (the difference between percentages in the sample, and the percentages in the universe from whence the sample is taken). The percentage error tends to go down as the square root of the size of the sample.
What are all the values that mean x bar can possibly take?
It can take any value between the maximum and minimum observed values.
The mode is the value that occurs most often. So just find what number appears the most and you have your mode. A good way to remember this is to think, mode = most.
18,24,24,26,30,30,30,38,44?
So in this case the mode is (30)
look at the figures the most comn figures will be the mode
e.g 10,13,14,8/10,10
the mode is 10
A spinney is a small wooded area or thicket of trees, shrubs, or bushes. It is a term often used to describe a small area of woodland or copse. Spinneys can provide a habitat for wildlife and can also be used for recreational purposes such as walking or birdwatching.
Several meanings, related to the idea of "holding something in custody". Check the English Wiktionary for more details.
First, I will give an example, similar to your question: -11000 -9000 +44000 mean = 8,000 and median = -9000. Symmetrical distributions after infinite sampling will show no difference in mean and median. Large differences are possible with small sample sizes even with symmetrical distributions. If the sample is large and the difference is large, this infers that the distribution is asymmetrical. The skewness of the distribution can be calculated.
What fraction of a yard is 3 inches?
Well... One yard = 3 ft = 36 inches. Thus, 3 inches is 1/12 of a yard.
What is the ratio of aces to the total number of cards in a standard deck of cards?
1-14 stupid, seriously, how stupid are you?
How many modes can a set of numbers have?
There can be as many modes as the number of observations.
If you roll a regular die 5 times and get 1, 2, 3, 4, 5 then each one of them is a mode. They all appear the most often - more than number 6 did.
If the next roll produced a six, there are either 6 modes or none. Opinions differ.

What age groups have the highest death rate in drivers?
17-25... simply because they're inexperienced, and (in many cases) immature. Additionally, they are more likely to take risks by their passengers inciting them to drive irrationally.
What is the purpose of data analysis in Excel?
Spreadsheets are for numerical analysis and manipulation. So in using Excel you would be doing a lot of analysis on numbers, like totalling them, averaging them, making charts from them, trying to determine trends from them, doing other calculations from them, comparing them and so on. Analysis of data is fundamental to computers. Spreadsheets do a lot of it with numerical data.

What is the advantages and disadvantages of multiple regression?
Advantages:
The estimates of the unknown parameters obtained from linear least squares regression are the optimal.
Estimates from a broad class of possible parameter estimates under the usual assumptions are used for process modeling.
It uses data very efficiently. Good results can be obtained with relatively small data sets.
The theory associated with linear regression is well-understood and allows for construction of different types of easily-interpretable statistical intervals for predictions, calibrations, and optimizations.
Disadvantages:
Outputs of regression can lie outside of the range [0,1].
It has limitations in the shapes that linear models can assume over long ranges
The extrapolation properties will be possibly poor
It is very sensitive to outliers
It often gives optimal estimates of the unknown parameters.
What does it mean for a product to have been pasteurized?
This means that the food has been treated in some manner to kill pathogens that may be present in it. This can be done with heat, chemicals, radiation, or pressure.
steady persistence in a course of action, a purpose, a state, etc., esp. in spite of difficulties, obstacles, or discouragement. 2. Theology. continuance in a state of grace to the end, leading to eternal salvation
