What is the number of samples for a distribution of sample means constructed by sampling 5 items from a population of 15?
the sampe mean cannot be comoputed
How do you calculate mean median and standard deviation?
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.
The standard error of the mean is the standard deviation of the sampling distribution of the sample mean?
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?
How do you find mean for a histogram?
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
What is the difference between a parameter and a statistic?
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!)
What is the mean for 8 12 15 11?
Mean = (sum of the samples) divided by (number of samples) = (8 + 12 + 15 + 11) / 4 = 46/4 = 11.5
How do you make a problem with mean median and mode?
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
What is the mean 55 52 74 63 67 60 49 49?
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.

What does it mean when green fluid is leaking from your vehicle?
Antifreeze is green in color and is leaking from your radiator .
For the scores 98 98 98 45 84 84 52 45 37 what is the mean?
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)
What is special about tanks in World War 2?
Not quite sure what you mean by 'special'. WWII tanks were certainly better than WWI tanks.
Did the Germans use blow up tanks?
I don't know what you mean by "blow up tanks," but I think the tanks blew stuff up =P
What is the word Emotional Tanks mean?
histrionic
What does it mean when antifreeze is leaking in a Chrysler Concorde?
If it is leaking inside the car, the heater core has failed.If it is leaking inside the car, the heater core has failed.

How do you filling pressure in Breathing appratus?
If you mean Scuba tanks, call a dive shop, if you mean emergency breathing tanks, call your local Fire Co.
