Dr. Stambaugh hypothesizes that a novel anxiety drug will affect
memory. To examine this, the drug is administered to a random
sample of 23 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 47 seconds. Normal rats have an average
completion time of 44 seconds with a standard deviation of 14
seconds. What can Dr. Stambaugh conclude with α = 0.01?
a) State the appropiate appropriate test statistic
(na, z-test, one sample t test, independent- samples t test,
related sample t test), population (normal rats, memory, trained
rats, time to complete maze, the maze), and sample (normal rats,
memory, trained rats, time to complete maze, the maze).
.
b) Compute the appropriate test statistic(s) to
make a decision about H0.
(Hint: Make sure to write down the null and alternative hypotheses
to help solve the problem.)
critical value = ; test statistic =
Decision: ---Select--- Reject H0 Fail to reject H0
c) If appropriate, compute the CI. If not
appropriate, input "na" for both spaces below.
[ , ]
d) Compute the corresponding effect size(s) and
indicate magnitude(s).
If not appropriate, input and select "na" below.
d = ; ---Select--- na, trivial effect ,small
effect ,medium effect , or large effect
r2 = ; ---Select--- na trivial
effect small effect medium effect large effect
Now, Make an interpretation based on the
results.
Rats on the anxiety drug were significantly slower completing the maze.
Rats on the anxiety drug were significantly quicker completing the maze. T
he anxiety drug did not affect rats in completing the maze.

Industrial Designs has been awarded a contract to design a label for a new wine produced by Lake View Winery. The company estimates that 150 hours will be required to complete the project. The firm’s three graphic designers available for assignment to this project are Lisa, a senior designer and team leader; David, a senior designer; and Sarah, a junior designer. Because Lisa has worked on several projects for Lake View Winery, management specified that Lisa must be assigned at least 40% of the total number of hours assigned to the two senior designers. To provide label designing experience for Sarah, the junior designer must be assigned at least 15% of the total project time. However, the number of hours assigned to Sarah must not exceed 25% of the total number of hours assigned to the two senior designers. Due to other project commitments, Lisa has a maximum of 50 hours available to work on this project. Hourly wage rates are $30 for Lisa, $15 for David, and $18 for Sarah.
