trapspacing-deployed by teams of fishermen. The trap- spacing measurements in meters) for a sample of seven teams from the Bahia Tortugas (BT) fishing cooperative are repeated in the table. In addition, trap-spacing mea- surements for eight teams from the Punta Abreojos (PA) fishing cooperative are listed. For this problem, we are interested in comparing the mean trap-spacing measure- ments of the two fishing cooperatives.

Shester, “Explaining Catch Variation Among Baja California Lobster Fishers Through Spatial Analysis of Trap-Placement Decisions," Bulletin of Marine Science, Vol. 86, No. 2, April 2010 (Table 1). a. Identify the target parameter for this study. b. Compute a point estimate of the target parameter. c. What is the problem with using the normal (z) statistic to find a confidence interval for the target parameter? d. Find a 90% confidence interval for the target parameter. e. Use the interval, part d, to make a statement about the difference in mean trap-spacing measurements of the two fishing cooperatives.
