Use Excel to find the Standard Normal Probability for the
following questions. Don't forget to sketch the normal distribution
and shade the required area. a) What is the area under the standard
normal curve to the left of z = 1.87? (4dp)
Answer b) What is the area under the standard normal curve
between z = -1.46 and z = 2.54? (4dp)
Answer c) What is the z-value that gives the right hand tail
area equal to 0.0384? (2dp)
Answer d) What is the absolute value of z such that the total
area under the standard normal curve between –z and +z will be
0.9946? (2dp) Answer
