How do you find the z value of an unknown Z with the standard normal distribution if P(|Z|≥z) is 0.05?

If an unknown Z has the standard normal distribution,
what is the number z with the property that
P (|Z| > 2)
is exactly .05? Use either stattrek.org or your text book
Table A.4 to calculate the answer to three decimal place
аccuracy.
