An article reported the following data on oxygen consumption (mL/kg/min) for a sample of ten firefighters performing a fire-suppression simulation: 28.8 49.4 30.0 28.8 28.2 26.4 34.0 29.0 23.6 31.3 USE SALT Compute the following. (Round your answers to four decimal places.) (a) The sample range mL/kg/min (b) The sample variance s 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) s' using the shortcut method mL2/kg2/min2The accompanying data represent the actual amount (in mL] poured into a tall, slender glass for individuals asked to pour 1.5 ounces (4-4.3 mL]. l use SALT Calculate the values ofthe mean and standard deviation [in mL). [Round your answers to four decimal places.) mean mL standard deviation mL Interpret the values of the mean and standard deviation. (Round your answers to four decimal places.) A typical amount poured into a tallr slender glass is |:| mL. A typical deviation from the mean amount poured is :l mL
