population mean of random variable y
x w/ line on top
sample mean of x
y w/ line on top
sample mean of y
σx
population standard deviation of random variable x
σx^2
population variable of random variable x
Sx
sample standard deviation
P(x=2)
probability that x = 2
X~N(7, 0.5)
RV x is distributed normally with a mean of 7 and a standard deviation of 0.5
Mean of distribution
affects the location of the curve on a number line
SD of distribution
affects the width of the curve on a number line
X~Bernoulli(0.6)
RV x is distributed Bernoulli with the probability of X=1 being 0.6
