What are the properties of z in a normal distribution?
Z is a variable with mean 0 and variance 1.Z is a variable with mean 0 and variance 1.Z is a variable with mean 0 and variance 1.Z is a variable with mean 0 and variance 1.
A fair coin is tossed 10 times what are the expected mean and variance of the number of heads?
mean = 5, variance = 5
How do you write a c program to calculate mean variance and standard deviation?
Program in CHere is a program in C to calculate mean variance and standard deviation: #include#includevoid main(){float a[50],sum=0,vsum=0,mean,variance,sd;int n,i;printf("Enter the no of valus");scanf("%d",&n);printf("Enter the no of valus");for(i=0;i
Are the mean and variance equal in the poisson distribution?
yes
Is in binomial distribution mean always greater then variance?
yes
What are the properties of z in a normal distribution?
Z is a variable with mean 0 and variance 1.Z is a variable with mean 0 and variance 1.Z is a variable with mean 0 and variance 1.Z is a variable with mean 0 and variance 1.
Can variance be negative?
Since Variance is the average of the squared distanced from the mean, Variance must be a non negative number.
When a coin is tossed four time then mean and variance of the number of the head?
Mean = 2. Variance = 1.
Is variance based on deviations from the mean?
Variance is the squared deviation from the mean. (X bar - X data)^2
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
A fair coin is tossed 10 times what are the expected mean and variance of the number of heads?
mean = 5, variance = 5
What is the sample variance with the mean of 190.3?
The mean, by itself, does not provide sufficient information to make any assessment of the sample variance.
How is standard deviation found?
Formally, the standard deviation is the square root of the variance. The variance is the mean of the squares of the difference between each observation and their mean value. An easier to remember form for variance is: the mean of the squares minus the square of the mean.
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

If the mean of a normal distribution is negative what is the varience?
The variance is always positive. The variance is not directly related to the sign (nor magnitude) of the mean.
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.
