(a) What is the relationship of the p-value and hypothesis
testing?
(b) What is a p-value threshold of 0.05 mean? (in words)
(c) Why do you think that a p-value of 0.05 is used so often as a
threshold? What is a situation when that value would be too large
(i.e. a value much lower than 0.05 should be used)?

8. Which of the following is a disciplined procedure for
systematic evaluation of the impact of potential failures and
thereby determining a priority of possible actions that will reduce
the occurrence of...
Explain the procedure
for testing a hypothesis using the P-value approach? What is the
criterion for judging whether to reject the null hypothesis?
6. What does the level
of significance represent in a test of hypothesis? Give an
example.
7. Explain the
difference between "accepting" and "not rejecting" a null
hypothesis.
The p-value method for hypothesis testing relies on the
fact that
if the null hypothesis is false, then it is very unlikely to
observe a p-value smaller than the chosen significance
level.
if the null hypothesis is true, then it is very unlikely to
observe a p-value larger than the chosen significance
level.
if the null hypothesis is true, then it is very unlikely to
observe a p-value smaller than the chosen significance
level.
if the alternative hypothesis is true,...
Consider the following research hypothesis and the p-value
obtained via a statistical test. Would this testing have involved
one-sample or two-sample hypothesis testing? Does the scenario
involved paired or independent samples? Assuming the appropriate
testing was used, what would be an appropriate conclusion to draw
given the reported results and p-value?
Explain the reasoning for your answers.
The hypothesis is that students who are familiar with the Theory
of Algorithms learn the programming language C++ faster than
students who are...

Explain how a hypothesis testing for a mean is similar to a
hypothesis test for a proportion. Then explain how z-test for a
mean is different than a t-test for a mean.
Find the hypothesis testing on a two population mean. Need a
T-test, interval and P-value focusing just on Gender not Rank or
Enlisted
Description: A sample of 299 testing the Ethics scores for a
sample of members of the U.S. Coast Guard by Gender (1=Male,
2=Female) and Rank (1=Officer, 2=Enlisted). Data simulated to match
cell means and standard deviation. Variables/Columns Gender 8 Rank
16 Ethics Score 18-24
