A sample of 26 offshore oll workers took part in a simulated escape exercise resulting in the accompanying data on time set 388 350 354 352 378 424 322 395 402 374 374 371 363 366 364 329 338 395 368 377 357 354 407 331 397 391 368 a Construct a stem and leaf display of the data Enter numbers from smallest to largest separated by spaces Enter NONE for stems with no values Stems Leaves 32 33 34 35 36 37 38 39 40 41 42 How does it suggest that the sample mean and median will compare The display is negatively skewed so the mean will be greater than the median The display is reasonably symmetric so the mean and median will be close The display is positively skewed so the median will be greater than the mean The display is negatively skewed so the median will be greater than the mean The display is positively skewed so the mean will be greater than the median b Calculate the values of the sample mean x and median 2 Hint Ex 9631 Round your answers to two decimal places B x sec 7 sec c By how much could the largest time currently 424 be increased without affecting the value of the sample median Enter if there is no limit to the amount By how much could this value be decreased without affecting the value of the sample median Enter If there is no limit to the amount d What are the values of x and when the observations are reexpressed in minutes Round your answers to two decimal places
