Essay

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: $$\begin{array} { l l l l l l l l } 373 & 370 & 364 & 366 & 364 & 325 & 339 & 393 \\356 & 359 & 363 & 375 & 424 & 325 & 394 & 402 \\392 & 369 & 374 & 359 & 356 & 403 & 334 & 397\end{array}$$
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.
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 mean?
d. What are the values of $\bar { x }$
and $\tilde { x }$
when the observations are re-expressed in minutes?
