As in the above program, the loc, scale, and size(two dimensional(3, 5), where 3 is the number of rows and 5 is the number of columns) values are passed to the normal() function, so the normal() function is generating the random samples from the normal distribution according to the passed values. If I have a random variable distributed Normally: x ~ Normal (mean,variance) is the distribution of the random variable still normal if I multiply it by a constant, and if so, how does it affect the mean and variance?

Scalar multiplication of a random variable. I have seen the use of an asterisk in the notation of radicals in radical chain reactions. where $\text{erf}$ is the error function. Multiplying a random variable by a constant increases the variance by the square of the constant. Avoiding alpha gaming when not alpha gaming gets PCs into trouble. The reason is that if we have X = aU + bV and Y = cU +dV for some independent normal random variables U and V,then Z = s1(aU +bV)+s2(cU +dV)=(as1 +cs2)U +(bs1 +ds2)V. Thus, Z is the sum of the independent normal random variables (as1 + cs2)U and (bs1 +ds2)V, and is therefore normal.A very important property of jointly normal random . 100 seems pretty obvious, and students rarely question the fact that for a binomial model = np .
