### Statistic problem

What is the area under the standard normal curve between z = -1.28 and z = 1.28? (4dp)

What is the z-value that gives the left hand tail area equal to 0.0102? (2dp)

What is the absolute value of z such that the total area under the standard normal curve between –z and +z will be 0.7924? (2dp)
