Lobster trap placement. Refer to the Bulletin of Marine Science (April 2010) observational study of lobster trap placement by teams fishing for the red spiny lobster in Baja California Sur, Mexico, Exercise 7.54 (p. 399). Trapspacing 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. 93 99 105 94 82 70 86 Source: G.

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 nonparametric 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. Applying the Concepts—Intermediate
