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 not familiar with this theory. We have gathered data from
30 students who are familiar with the Theory of Algorithms (Group
1) and 30 students who are not familiar with the Theory of
Algorithms (Group 2). Experiments showed students from Group 1 took
a mean of 32.5 hours to complete the training course of C++, while
students Group 2 the mean was 42.1 hours. The p-value was 0.14.

predetermined alpha value.

your margin of error (make it smaller) then it requires a
__________ sample size.

In which case would testing the null hypothesis not involve a
one-tailed statistical test? PLEASE PROVIDE BRIEF EXPLANATION!
H1: Incentive pay for teachers does affect student
achievement
H1: Higher sales tax rates does not reduce state tax
revenues

increase the length of joblessness

(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)?
