P(0<z<1.77)=

Solutions

Expert Solution

Solution:

We have to find:

P(0 < z < 1.77)=...........?

P(0 < z < 1.77)= P( z < 1.77) - P( Z< 0)

Look in z table for z = 1.7 and 0.07 as well as for z = 0.0 and 0.00 and find corresponding area.

P( Z< 1.77 ) = 0.9616

and

P( Z < 0.00) = 0.5000

thus

P(0 < z < 1.77) = P( z < 1.77) - P( Z< 0)

P(0 < z < 1.77) = 0.9616 - 0.5000

P(0 < z < 1.77) = 0.4616
