A sensitive measuring device is calibrated so that errors in the measurements it provides are normally distributed with mean 0 a

Artemon [7]

Answer: 0.9660

Step-by-step explanation:

Given: Mean : $\mu =0$

Variance : $\sigma^2=2.00$

⇒ Standard deviation : $\sigma = \sqrt{2}$

The formula to calculate z is given by :-

$z=\dfrac{x-\mu}{\sigma}$

For x= -3

$z=\dfrac{-3-0}{\sqrt{2}}=-2.12132034356\approx-2.12$

The P Value = $P(z$

For x= 3

The P Value = $P(z$

$\text{Now, }P(-3$

Hence, the probability that a given error will be between -3 and 3=0.9660
