the sampe mean cannot be comoputed
The mean is the sum of each sample divided by the number of samples.The median is the middle sample in a ranked list of samples, or the mean of the middle two samples if the number of samples is even.The standard deviation is the square root of the sum of the squares of the difference between the mean and each of the samples, such sum then divided by either N or by N-1, before the square root is taken. N is used for population standard deviation, where the mean is known independently of the calculation of the standard deviation. N-1 is used for sample standard deviation, where the mean is calculated along with the standard deviation, and the "-1" compensates for the loss of a "degree of freedom" that such a procedure entails.Not asked, but answered for completeness sake, the mode is the most probable value, and does not necessarily represent the mean such as in an asymmetrically skewed distribution, such as a Poisson distribution.
a large number of samples of size 50 were selected at random from a normal population with mean and variance.The mean and standard error of the sampling distribution of the sample mean were obtain 2500 and 4 respectivly.Find the mean and varince of the population?
You need to add all the values shown on the histogram and then divide that sum by the number of values (samples). Example: There are 5 values: A, B, C, D, E. Mean value is: (A+B+C+D+E) / 5
A parameter is a number describing something about a whole population. eg population mean or mode. A statistic is something that describes a sample (eg sample mean)and is used as an estimator for a population parameter. (because samples should represent populations!)
Mean = (sum of the samples) divided by (number of samples) = (8 + 12 + 15 + 11) / 4 = 46/4 = 11.5
mean is just if you sum up all samples and divide it by the number of samples median is the one in the middle. so you could sort your samples and then "delete the highest and lowest" until you only have one mode is the thing i can't remember
Mean is synonymous with average. It is the sum of all the samples divided by the number of samples. The sum of the eight numbers is 469, and 469 divided by 8 equals 58.625.

Antifreeze is green in color and is leaking from your radiator .
Mean = "average" = (sum of samples) / (number of samples)Mean = (1/9) x (98 + 98 + 98 + 45 + 84 + 84 + 52 + 45 + 37) = 641/9 = 71.222 (rounded, repeating)
Not quite sure what you mean by 'special'. WWII tanks were certainly better than WWI tanks.
I don't know what you mean by "blow up tanks," but I think the tanks blew stuff up =P
histrionic

If you mean Scuba tanks, call a dive shop, if you mean emergency breathing tanks, call your local Fire Co.
