Transcribed Image Text:An article reported the following data on oxygen consumption (mL/kg/min) for a sample of ten firefighters performing a fire-suppression simulation:
28.3 49.2 30.1 28.8 28.4 25.8 33.3 29.0 24.0 30.4
A USE SALT
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/kg?/min?
(c) The sample standard deviation
mL/kg/min
(d) s using the shortcut method
mL2/kg?/min?
Expert Solution
Step 1
We know that
First Arrange data in ascending order.
24.0, 25.8, 28.3, 28.4, 28.8, 29.0, 30.1, 30.4, 33.3, 49.2
Range = maximum - minimum
NOTE:- According to bartleby guidelines expert can solve maximum three subparts of a question and rest can be reposted please
