Which of the following is not true?
a. if values are converted to standard z-scores, then procedures for working with all normal distributions are the same as those for the standard normal distribution.
b. a z-score is a conversion that standardizes any value from a normal distribution to a standard normal distribution.
c. a z-score is an area under the normal curve.
d. the area in any normal distribution bounded by some score x is the same as the area bounded by the equivalent z-score in the standard normal distribution.

step-by-step explanation:

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
