mean of 10 and a variance of 30

How can i distribution is normal with a mean of 10 and a variance of 30.(for n samples;n=50)

[John D'Errico]

Did you read the help for normrnd? Why not? Is ithis homework? Almost certainly.

[S.M]

size =[1 50] ;

sigma = 30 ;

mu = 10 ;

X = normrnd(mu,sigma,size);

is it true?

Try this:

n = 50;
r = 10 + 30 * randn(1, n);
theActualMean = mean(r)

theActualMean = 11.4852

theActualSD = std(r)

theActualSD = 33.1631
