Question

Emily is a fifth-grade student who completed a standardized reading test. She scored one standard deviation above the mean score. How does the normal curve help you understand what this means about how your child compares to other children who took the test? Explain how you determined your findings. How many children scored lower than your child? How many scored higher?

Answer #1

**Here' is the answer to the question. I've explained in
detail the answer and the source of it. Please don't hesitate to
give a "thumbs up" for the answer the question in case you're
satisfied.**

Emily has scored one standard deviation above mean score.

According to this, the n**ormal curve' distribution says
that** if Emily score is 1 deviation above mean then there
are 32% of students have scored more than her and 68% of people
have scored less than her. The empirical rule states that
68%-95%--99.7% of the area is under the curve for 1, 2 and 3
standard deviations from the mean.

So, we have derived our finding from the general empirical rule of normal curve.

Emily is a fifth-grade student who completed a standardized
reading test. She scored one standard deviation above the mean
score. How does the normal curve help you understand what this
means about how your child compares to other children who took the
test? Explain how you determined your findings. How many children
scored lower than your child? How many scored higher?

6. When a standardized test was scored, there was a mean of 500
and a standard deviation of 100. Suppose that 10,000 students took
the test and their scores had a bell-shaped distribution, making it
possible to use a normal curve to approximate the distribution.

2).____________________ How many scored between 300 and 700?
3)____________________ How many scored above 800?

A reading specialist wants to identify third-graders who scored
at the lowest 10% on a standardized reading test in elementary

the program you're applying to requires you get the
90th percentile in thier standardized test . the mean score for
those taking it is 747 and its scores are normally distributed with
a standard deviation of 77.
1) what must you score on the test to be admitted into
your program?
2) at what percentile is your friend who scored
850?
3) if 1000 people take the test how many people lay
between your score and your friend's?

(3 pts) For students in a certain region, scores of students on
a standardized test approximately follow a normal distribution with
mean μ=543.4 and standard deviation σ=30. In completing the parts
below, you should use the normal curve area table that is included
in your formula packet.
(a) What is the probability that a single randomly selected
student from among all those in region who took the exam will have
a score of 548 or higher?
