Textbook Question
Chapter 15.2, Problem 15.10ACB
Lobster trap placement. Refer to the Bulletin of Marine Science (April 201 0) observational study of lobster trap placement by teams fishing for the red spiny lobster in Baja California Sur. Mexico, Exercise 7.54 (p. 393). Trap-spacing measurements (in meters) for a sample of seven teams of red spiny lobster fishermen are reproduced in the accompanying table. In Exercise 7.54, you tested whether the average of the trap-spacing measurements for the population of red spiny lobster fishermen fishing in Baja California Sur, Mexico, differs from 95 meters.
- a. There is concern that the trap-spacing data do not follow a
normal distribution . If so, how will this impact the test you conducted in Exercise 7.54? - b. Propose an alternative non parametric test to analyze the data.
- c. Compute the value of the test statistic for the nonparametric test.
- d. Find the p-value of the test.
- e. Use the value of a you selected in Exercise 7.54 and give the appropriate conclusion.

The article “Dynamics of Insulin Action in Hypertension: Assessment from Minimal ModelInterpretation of Intravenous Glucose Tolerance Test Data” (R. Burattini, M. Morettini, etal., Med Biol Eng Comput, 2011:831–841) compared levels of an insulin sensitivity index SIin patients with high blood pressure and patients with normal blood pressure. Ten patientswith high blood pressure had a mean value of 3.4 with a standard deviation of 0.6, and eightpatients with normal blood pressure had a mean value of 7.9 with a standard deviation of0.6. Units are 10−5 · min−1 · pmol−1. Find a 98% confidence interval for the difference inmean levels between those with high blood pressure and those with normal blood pressure.
A researcher conducted a repeated measures study comparing three treatment conditions. Refer to attached images and tale to answer a to d.

In APA format, report the F-ratio related to the treatment effect:
Is this treatment effect significant?
What is the partial η2 value for the treatment effect?
Is this a weak, moderate, or strong effect?
In a study examining the effect of alcohol on reaction
time, Liguori and Robinson (2001) found that even
moderate alcohol consumption significantly slowed
response time to an emergency situation in a driving
simulation. In a similar study, researchers measured
reaction time 30 minutes after participants consumed
one 6-ounce glass of wine. Again, they used a stan
dardized driving simulation task for which the regular
population averages μ = 400 msec. The distribution of
reaction times is approximately normal with σ = 40.
Assume that the researcher obtained a sample mean of
M = 422 for the n = 25 participants in the study.
a. Are the data sufficient to conclude that the alcohol
has a significant effect on reaction time? Use a
two-tailed test with α = .01.
b. Do the data provide evidence that the alcohol
significantly increased (slowed) reaction time? Use
a one-tailed test with α = .01.
c. Compute Cohen’s d to estimate the size of the
effect.
