  1. Draw a vertical line through a normal distribution for each of the following z-score locations. Determine whether the tail is on the right or left side of the line and find the proportion in the tail.
  • z = 1.00
  • z = –0.40.

Expert Answer

Step 1

1(a) The provided z value is 1.00 for which the graph is shown below,

Step 2

The vertical is passing through z =1which lies in the right tail as the value of z is falling in the right portion of the graph.

The required probability is,

P(Z 1)=1-P(Z1) (Using standard normal table) 1-0.8413 =0.1587

Step 3

1(b) The provided z value is -0.40 for ...
