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 in the right hand tail of the standard normal curve beyond z = 1.02? (4dp)
b) What is the area under the standard normal curve between z = -1.94 and z = 0.00? (4dp)
c) What is the z-value that gives the left hand tail area equal to 0.1492? (2dp)
d) What is the absolute value of z such that the total area under the standard normal curve between –z and +z will be 0.6578? (2dp)
