Answer #1

Answer)

A)

As here we need to test if personality score increase the confidence.

It is a dependant variable.

B)

Within subjects means repeated measure.

Between subjects means each and every observation required to be tested only once.

So here we have between subjects.

C)

It is an one tailed test (right tailed)

We need to see if there is an increase, so we have a direction here.

If we have to see if there is difference then it is a two tailed.

But here it is one tailed.

The main goal is to implement two recursive methods, each is built to manipulate linked data structures. To host these methods you also have to define two utterly simplified node classes. 1.) Add a class named BinaryNode to the project. This class supports the linked representation of binary trees. However, for the BinaryNode class Generic implementation not needed, the nodes will store integer values The standard methods will not be needed in this exercise except the constructor 2.) Add a...

T-tests are used when you want to examine differences but you do not know everything about the population. There are three types of t-tests that you may choose to do: one-sample t-test, independent sample t-test, or dependent sample t-test. You can calculate these by hand, in SPSS, or in Excel. The instructions below can be used for SPSS and your textbook offers instructions for using Excel. Single-sample t-tests These tests are used when you want to determine the probability that...

As you saw from the lab PowerPoint slides last week, you will be doing a research study looking at ‘Aggression Priming” for your first paper. For this week’s discussion, I want you to discuss with your group what you think this study is about. What is the hypothesis? What theory does it come from? What do you predict will happen (do you expect something different than the hypothesis in the researcher instructions? If so, what and why?)? Do you think...

A debate rages whether or not bottled water is worth the cost. The National Resource Defense Council concludes, “there is no assurance that bottled water it is any cleaner or safer than tap (water).” But, in addition to the safety issue, many people prefer the taste of bottled water to tap water, or so they say! Let’s suppose that the city council members of Corvallis are trying to show that the city of Corvallis tap water tastes just as good...
