1. Given that z is the standard normal variable (with mean 0 and standard deviation 1), find
(a) P(0 = z = 1.75) (b) P(-1.29 = 2 = 0)
(c) P(1.03 = z = 1.21) (d) P(z = 2.31)
(e) P(Z < -1.96)
(f) P(z = 1.00)

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"
