Type or paste question hereConsider the following. (Give your answers correct to four decimal places.)

(a) Find P(0.00 < z < 2.08).

(b) Find P(-1.83 < z < 2.09).

(c) Find P(z > 0.21).

(d) Find P(z < 1.53).

Expert Solution

Let z follows standard normal distribution.

P(a<z<b) =(b) - (a)

From table we can find the value of (.)

a)P(0.00<z<2.08)

=(2.08)-(0.00)

=0.9812-0.5000

=0.4812

b)P(-1.83<z<2.09)

=(2.09) - (-1.83)

=0.9817-0.0336

=0.9481

c)P(z>0.21)

=1-P(z<0.21)

=1-(0.21)

=1-0.5832

=0.4168

d)P(z<1.53)

=(1.53)

=0.9370
