Chapter 1, Problem 1.36(choose chapter or problem)
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: 281292): 389 356 359 363 375 424 325 394 402 373 373 370 364 366 364 325 339 393 392 369 374 359 356 403 334 397 a. Construct a stem-and-leaf display of the data. How does it suggest that the sample mean and median will compare? b. Calculate the values of the sample mean and median. [Hint: xi 9638.] c. By how much could the largest time, currently 424, be increased without affecting the value of the sample median? By how much could this value be decreased without affecting the value of the sample median? d. What are the values of x and when the observations are reexpressed in minutes?
