which value is used to calculate variance from a normal distribution which of the following is an estimated parameter in normal distribution? ____ is the parameter of the sample normally distributed with the mean $mu$ and variance $sigma2$. what is the value of the variable variance in a normal distribution i have a normal variance of the value of x and the parameter when do you use the first estimator in a normal distribution? how to get parameter estimation variance variance how to estimate normal distribution how to find a parameter estimate for the random variable what property is used to estimate variance what is the second parameter estimation for variance what is the function of the estimator in normal distributions? which parameter estimator is used to compare the variance and mean of a variable? what is the parameter for the barx average variance from a normal distribution what is the expected value of variance in an independent sample what is the property of the first parameter in a normal distribution if a parameter is not biased what is parameter estimation
