Question

Answer the following. The guide on how to solve is already indicated.

Step 1
Draw the figure and indicate the
appropriate area.
Step2
Find the z value which corresponds to the area
Given
A left-tailed test with
a =0.10.
Find the area closest to 0.1000 in z table. In
this case, it is 0.1003 the z value which
corresponds to the area 0.1003. It is -1.28.
