You are given the results of measurement of resistors. We are testing the
measurement tool. It will pass the technical control if the mean value will be
in the range [198-202] with standard deviation less than 3 Ohms. Will the tool
pass the technical control?

Answer 1

As both the standard deviation and the mean have the desired values, the tool passes the technical control.

Explanation:

Mean:

The mean is the sum of all values divided by the number of values.

`M = (199+204+201+197+195+204+200)/(7) = 200`

The mean is in the desired range.

Standard deviation:

The standard deviation is the square root of the sum of the difference squared between each value and the mean, divided by the number of values.

`S = \sqrt{((199-200)^2+(204-200)^2+(201-200)^2+(197-200)^2+(195-200)^2+(204-200)^2+(200-200)^2)/(7)} = 1.18`

As both the standard deviation and the mean have the desired values, the tool passes the technical control.
