How do you find the z score of 12.5?
To find the Z score from the random variable you need the mean and variance of the rv.To find the Z score from the random variable you need the mean and variance of the rv.To find the Z score from the random variable you need the mean and variance of the rv.To find the Z score from the random variable you need the mean and variance of the rv.
Suppose the variance is 64 Find the standard deviation?
Standard deviation is the square root of the variance; so if the variance is 64, the std dev is 8.
(b)For a set of numbers 1,4,7. Find population mean and Variance. Draw up frequency distributions of means of all possible samples of size 3 when sampling is carried out with replacement. Find mean and variance of distribution?
lowest
How do you calculate a budget variance as a percentage?
actual budget/budget = variance%
What is the meaning of analysis of covariance?
A mix of linear regression and analysis of variance. analysis of covariance is responsible for intergroup variance when analysis of variance is performed.
How do you compute market price variance?
Price Variance = (Actual Price/Unit - Budgeted Price/Unit) x Actual Quantity of Output = (AP - SP) x AQ
Suppose the standard deviation is 36 Find the variance?
Variance is 362 or 1296.

Is variance the square root of standard deviation?
No, you have it backwards, the standard deviation is the square root of the variance, so the variance is the standard deviation squared. Usually you find the variance first, as it is the average sum of squares of the distribution, and then find the standard deviation by squaring it.
Suppose the variance is 64 Find the standard deviation?
Standard deviation is the square root of the variance; so if the variance is 64, the std dev is 8.
How do you find range when all you have is the variance?
You cannot.
What is cost price variances?
Price variance is the actual unit cost minus the standard unit cost, multiplied by the actual quantity purchased. The variance is said to be unfavorable if the actual price of the materials is higher than the standard price of the materials.
How do you do variance?
you have to first find the Mean then subtract each of the results from the mean and then square them. then you divide by the total amount of results and that gives you the variance. If you square root the variance you will get the standard deviation
What is difference between the amount budgeted and the actual amount is called?
Difference between actual amount and budgeted amount is called "Variance" and variance analysis is done to find out the reasons for variance
How do you work out variance?
you have to first find the Mean then subtract each of the results from the mean and then square them. then you divide by the total amount of results and that gives you the variance. If you square root the variance you will get the standard deviation
