Question

The Board of Trustees believe that test anxiety is increased by
the time spent in college. After completing their sophomore year, a
random sample of students was selected and given the College Test
Anxiety Questionnaire (CTAQ). After completing their senior year
they were again tested. What can be conclude with α =
0.05?

sophomore |
senior |

5.9 7.2 7.4 6.8 8.5 6.2 6.1 5.2 |
2.1 7.5 3.2 6.3 5.5 6.4 4.6 5.2 |

**a)** What is the appropriate test statistic?

---Select: na, z-test, One-Sample t-test, Independent-Samples
t-test, or Related-Samples t-test

**b)**

Condition 1:

---Select: senior, time in college, sophomore, test anxiety, or
CTAQ

Condition 2:

---Select: senior, time in college, sophomore, test anxiety, or
CTAQ

**c)** Input the appropriate value(s) to make a
decision about *H*_{0}.

(Hint: Make sure to write down the null and alternative hypotheses
to help solve the problem.)

*p*-value? = ; Decision?: ---Select---
Reject H0 Fail to reject H0

**d)** Using the **SPSS** results,
compute the corresponding effect size(s) and indicate
magnitude(s).

If not appropriate, input and/or select "na" below.

*d?* = ; ---Select: na, trivial effect, small
effect, medium effect, or large effect

*r*^{2?} = ; ---Select-: na, trivial
effect, small effect, medium effect, or large effect

**e)** Make an interpretation based on the
results.

(a)Students showed significantly more test anxiety in their sophomore year than their senior year.

(b)Students showed significantly less test anxiety in their sophomore year than their senior year.

(c)Students did not significantly differ in their test anxiety between their senior and sophomore year.

Dr. Yan predicts that a novel antidepressant drug improves
cognition. To examine this, the drug is administered to a random
sample of 28 trained rats. The rats were then placed in a maze and
timed on how long it took them to complete it. The average
completion time was 48 seconds. Normal rats have an average
completion time of 44 seconds with a variance of 100.00 seconds.

Dr. Chase wants to investigate how cell phone use impacts
reaction time. To test this, Dr. Chase conducted a study where
participants are randomly assigned to one of two conditions while
driving: no cell phone or cell phone. Participants were then
instructed to complete a driving simulator course where reaction
times (in milliseconds) were recorded by how quickly they hit the
breaks in response to a dog crossing the middle of the road during
the course. Below are the data....

A study was conducted using undergraduates at a rural university
who volunteered to participate in the research as partial

alcohol consumption between freshmen and juniors. Based on the
information in the table below, what can be concluded with α =
0.05?
