multiplying normal distribution by constant

The standard deviation will remain unchanged. Mathematically, you should be noticing that the argument of the exponential in the PDF is a function of $x/\sigma$, not just $x$ or $\sigma$ alone, and that the differential element is actually $d(x/\sigma)=dx/\sigma$.

Expected value of a constant. Multiplying a random variable by a constant (aX) Adding two random variables together (X+Y) Being able to add two random variables is extremely important for the rest of the course, so you need to know the rules. 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 . $Z = X + X$ is also normal, i.e. Z scores The z score provides the exact position of a score in its distribution.
