Question

Find the range and the standard deviation of the following voltages (in volts. of a sample of watch batteries: 1.212, 1.199, 1.201, 1.202, 1.199, 1.198.
A. Range = 0.014 V; standard deviation = 0.0040 V

B. Range = 0.013 V; standard deviation = 0.0039 V

C. Range = 0.013 V; standard deviation = 0.0040 V

D. Range = 0.014 V; standard deviation = 0.0052 V

Answer 1

range = max-min = .014

standard dev ...use calculator or if you need to know by hand i will show you the formula
= .0052

Answer 2

thanks
