An article reported the following data on oxygen consumption (mL/kg/min) for a sample of ten firefighters performing a fire-suppression simulation:
Compute the following. (Round your answers to four decimal places.)
(a) The sample range
mL/kg/min
(b) The sample variance s2 from the definition (i.e., by first computing deviations, then squaring them, etc.)
mL2/kg2/min2
(c) The sample standard deviation
mL/kg/min
(d) s2 using the shortcut method
mL2/kg2/min2
