Standard Normal Distribution Table
Use the Normal Table to find the following:
a) Probability (z < 2.65)
b) Probability (z > 1.55)
c) Probability (2.00 < z < 2.25)
d) Probability ( 1.25 < z < 2.40)
Please show the steps you used to get to the answers.

Solution Preview
a) Probability (z < 2.65)
In the tables prob values for only positive z is given
We will look up Cumulative probability for Z = 2.65
This is equal to 0.4960
This means the probability from z=0 to z= 2.65 is 0.4960
Since the normal distribution is symmetric this is also equal to probability from z=0 to z= 2.65
Probability (z < 2.65) = 0.5  Prob ( Z= 0 to ...
Solution Summary
Using standard normal distribution table has been used to calculate probabilities in the solution.
