1. Arachni has its own system for scoring vulnerability
severity. Which vulnerabilities do you think are the most
severe/critical? Which are the least severe/critical?
2. How would you categorize the Windows Server that you
scannedÑa server that stores and processes health dataÑin terms of
its criticality?
3. "If you had to summarize the state of the BxB web app to
GCPG's executives, what would you say?"
What is meant by the term significance? How is significance
level related to what you learned in previous chapters about
probability? Please provide an example using significance in your
work or life.
What is the main use of a one sample Z-Test? Please provide an
example.
• What is the level of significance? • What are Type I and Type
II errors? • Interpreting and determining p-values • What is the
relationship between sample size and power? • Understand the
difference between a p-value and a confidence interval—strengths
and weaknesses
What is the decision at a 0.05 level of significance for each
of the following tests? Hint: Find the critical value for
each test; then make a decision. (Round your critical values to two
decimal places.)
F(3, 28) = 2.98
F(5, 17) = 2.63
F(2, 10) = 4.02
F(4, 33) = 2.69

decimal places.)

Fcrit =
F(5, 15) = 2.67

What is the level of significance of a
test?
the probability σ of rejecting H1 when it is
true
the probability α of failing to reject H0
when it is true
the probability α of rejecting H1 when it is
true
the probability α of rejecting H0 when it is
true
the probability α of failing to reject H1
when it is true
What is the P-value?
the probability that the observed test statistic will take on
values less extreme...
