Q1-. A normal distribution has a mean of 15 and a standard
deviation of 2. Find the value that corresponds to the 75th
percentile. Round your answer to two decimal places.
Q2-.Tyrell's SAT math score was in the 64th percentile. If all
SAT math scores are normally distributed with a mean of 500 and a
standard deviation of 100, what is Tyrell's math score? Round your
answer to the nearest whole number.
Q3-.Find the z-score that cuts off an area...

Using the Standard Normal Table found in your textbook, find the
z-scores such that: (a) The area under the standard normal curve to
its left is 0.5 z = (b) The area under the standard normal curve to
its left is 0.9826 z = (c) The area under the standard normal curve
to its right is 0.1423 z = (d) The area under the standard normal
curve to its right is 0.9394

Find the area under the standard normal curve that lies between
the following two z values. Round your answers to at least four
decimal places.
(a)Find the area under the standard normal curve that lies
between = z − 1.28 and = z 1.36 .
(b)Find the area under the standard normal curve that lies
between = z − 2.17 and = z − 1.92 .
(c)Find the area under the standard normal curve that lies
between = z 1.36...

a. Find z such
that 24% of the standard normal curve lies to the right of z.
b. Find the z values such that 64% of the standard normal curve
lies between –z and z
c. Find z such that 36% of the standard normal curve lies to the
left of z

Find the area under the standard normal curve to the left of
z=−2.83 and to the right of z=2.15. Round your answer to four
decimal places, if necessary.

Using the standard normal distribution determine:
a) The area under the curve to the left of z=-2.38
b) The area under the curve to the right of z=1.17
c) The area under the curve between z=-1.52 and z=2.04

Find the area under the standard normal curve to the left of
z=−1.51z=−1.51 and to the right of z=1.4z=1.4. Round your answer to
four decimal places, if necessary.

Please answer the questions below
