PROB AND STATS

Question 1

Is a normal probability that has a mean
µ = 0 and a standard deviation 𝜎 = 1.

Answer 1

STANDARD NORMAL CURVE

Question 2

The table of areas under the normal
curve is also known as z – table.

Answer 2

Z-TABLE

Question 3

Is a measure of relative standing. It
represents the distance between a
given measurement and the mean,
expressed in standard deviation.

Answer 3

Z-SCORE

Question 4

s a measure of relative standing.
These scores represent distances from
the center measured in standard
deviation units. There are six z-scores
at the base of the normal curve. Three
z – scores to the left of the mean and
three z – scores to the right of the
mean.

Answer 4

Z-SCORE

Question 5

The areas under the normal curve are
given in terms of 2 – value or scores.
Either the z – score locates X within a
sample or within a population.

Answer 5

Z-Score

Question 6

a frequency using
the means computed from all possible
random samples of a specific size
taken from the population.
• The number of samples of size
n that can be drawn from a
population of size n is given by
N
C
n.

Answer 6

SAMPLING DISTRIBUTION OF
SAMPLE MEAN

Question 7

The difference between the
sample means and the
population mean is called

Answer 7

SAMPLING ERROR

Question 8

The value of a random variable

Answer 8

X

Question 9

The probability of the random variable
X.

Answer 9

P(X)
