Math, microeconomics or criminal justice
P(z>1.94) = .02619 = 2.619%
by the empirical rule P(-2<z<2) = 95% = .95
add .05/2 = .025. .95+.025 = .975
subtract from 1
1-.975 = .025 = 2.5%
P(z>1.94) is slightly greater than P(z>2)
2.619% is slightly greater than 2.5%
use z tables or an online z calculator
