Set of 25 numbers has standard deviation 6 then it's variance is?
Square the standard deviation to obtain the variance. The variance is 62 or 36.
When two dice are thrown let X be the larger of the two numbers on the two throws find the probability distribution mean and variance of X?
The probability distribution is P(X = 1) = 1/36 P(X = 2) = 3/36 P(X = 3) = 5/36 P(X = 4) = 7/36 P(X = 5) = 9/36 P(X = 6) = 11/36 P = 0 otherwise. Mean(X) = 4.4722 Variance = 1.9715
A fair die is rolled 36 times What is the standard deviation of the even number 2 4 or 6 outcomes?
Every roll of a fair die has a one in two chance of being even or odd.
How do you find the variance 415 10 8 33 25 36 66 63 50 64 49 40?
First mean is calculated.Then calculate deviations from the mean.Then the deviations are squared.Then the squared deviations are summed up.Finally this sum is divided by number of items for which the variance is being calculated. For a population, it is by the number of values, in this case 12. If it is a sample, then we divide by one less, which is 11,For these figures, the variance for the population is 11069.24306. If it is a sample, it is 12075.53788 as the result.
What is the standard deviation for the following numbers 100 76 68 80 56 64 72 52 84 40 60 72 56 64 36 52 76 44 60 80 56 48 68 76 84?
