X denotes a normally distributed random variable: X ~ N(m, s). The random variable Z denotes a standard normal random variable, Z ~ N(0,1).

1. Probability of X being less than its mean
2. SD of Z
3. Probability that Z > 1.96 plus the probability that Z < -1.96

Options.
A. 1/2
B. 1
C. 0.05

Answer 2

lol .... yay stats!!! .. helps to break up the algebra monotony

Answer 3

LOL

Answer 4

N means normal distributionl (mean,sd) is the other part for the notation

Answer 5

Probability of X being less than its mean is .5; since the probability up to the mean is simply .5

Answer 6

the SD of Z, is notated as 1

Answer 7

Probability that Z > 1.96 plus the probability that Z < -1.96
