Sampling and sampling distributions are the basis of statistical
analysis, and they are also important parts of applied business
statistics. Therefore, designing an effective sampling plan is
crucial to get representative samples of the population under
study.
Explain the role that a sample plays in making statistical
inferences about the population. Give an example of a sampling
survey for a business study, and briefly discuss how the projected
sampling results could have an effect on the business’ pricing
strategies and...
name two statistical distributions that are commonly used to
describe the statistical properties of the flat fading channels.
and explain their simmilarities and the differences.
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.

Detail one instance in which regression analysis can be used in
a business application. Explain what insights can be gained,
limitations that must be considered, and outline one case example
used in real life.
1- Regression analysis can be described as ________. A. a
statistical hypothesis test in which the test statistic follows a
Student's t-distribution if the null hypothesis is supported B. a
collection of statistical models in which the observed variance in
a particular variable is partitioned into components attributable
to different sources of variation C. a statistical hypothesis test
in which the sampling distribution of the test statistic is a
chi-square distribution when the null hypothesis is true D. a tool...

Explain in detail why is it important for a normal, rational
investor to hold a fully diversified portfolio. Use precise
language (correct finance terminology) and describe what happens in
your portfolio as you go from holding one stock to being fully
diversified. DO NOT use the wording "put all your eggs in one
basket" at any time in your answer or you will suffer a 5-point
penalty.
