In: Statistics and Probability
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
