1. A sample of 26 offshore oil workers took part in a simulated escape exercise, resulting in the accompanying data on time (sec) to complete the escape. ("Oxygen Consumption and Ventilation During Escape from an Offshore Platform," Ergonomics, 1997 281-292) Check sum= 9638 (The sum of all the data is 9638. Use this value as a double check that you enter data correctly.) 389 424 373 325 374 397 356 325 370 339 359 359 394 364 393 356 363 402 366 392 403 375 373 364 369 334 A) Which measure of central tendency should you use with this data? Explain your reasoning. B) Which measure of variation should you use with this data? Explain your reasoning. C) Using JMP, a calculator, or by hand, obtain the following statistics for this data: mean, median, mode, standard deviation, range, first and third quartiles, and the IQR. D) Using JMP or by hand, create a boxplot of the data. Be sure to label the minimum, maximum, median, quartiles and any outliers. **JMP instructions are posted on Scholar. I strongly recommend that you at least practice with JMP and look at the output format. 1.
