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=Highest entry-Lowest entry

Now to find the standard deviation you are gonna have to use this formula:

Answer 2

what

Answer 3

To find the range, subtract the lowest entry from the highest entry
