How do you find the total area under the normal distribution
curve between, for example, -2.25 and 2.25? Listing steps on how to
solve this would be great. Thank you!!
Find an example of application of Normal Distribution (or
approximately Normal Distribution) in your workplace or business or
any example of Normal Distribution. Prove that the variable has the
characteristics of a Normal Distribution. Recall that the variable
must be continuous and the distribution must be symmetrical (or
approximately symmetrical). To prove that the distribution is
approximately symmetrical select 20 random observations
(measurements/data) of the variable and run a Descriptive
Statistics using your calculator or Excel. Just copy the output...
For the following binomial distributions, determine if you can
approximate with a normal distribution. Then, find the given
probabilities.
a) A survey of US adults found that 55% are familiar with the
Geneva Conventions and international humanitarian law. You randomly
select 40 US adults and ask them whether they are familiar with the
Geneva Conventions and international humanitarian law. Find the
probability that between 18 and 25, inclusive, are familiar with
the Geneva Conventions and international humanitarian
law.
Can you...
Determine whether you can use the normal distribution to
approximate the binomial distribution. If you can, use the normal
distribution to approximate the indicated probabilities and sketch
their graphs. If you cannot, explain why and use the binomial
distribution to find the indicated probabilities.
A survey of adults in a region found that
52
%
have encountered fraudulent charges on their credit cards. You
randomly select
100
adults in the region. Complete parts (a) through (d)
below.

Decide whether you can use the normal distribution to
approximate the binomial distribution. If you can, use the normal
distribution to approximate the indicated probabilities and sketch
their graphs. If you cannot, explain why and use the binomial
distribution to find the indicated probabilities. Five percent of
workers in a city use public transportation to get to work. You
randomly select 269 workers and ask them if they use public
transportation to get to work.
