An article reported the following data on oxygen consumption (mL/kg/min) for a sample of ten firefighters performing a fire-suppression simulation:
| 29.9 |
49.8 |
30.7 |
28.3 |
28.8 |
25.4 |
33.7 |
29.5 |
23.1 |
30.5 |
Compute the following. (Round your answers to four decimal places.)
(a) The sample range
mL/kg/min
(b) The sample variances2from the definition (i.e., by first computing deviations, then squaring them, etc.)
mL2/kg2/min2
(c) The sample standard deviation
mL/kg/min
(d)s2using the shortcut method
mL2/kg2/min2
