Given : using a left tailed test,
To Find : which of the following value of z falls in the rejection region where the critical value is -1.725
Solution:
using a left tailed test, Values on right region of critical value are not in rejected region.
But values less than critical value ( Region in the left of region upto critical value will be rejection region )
Hence -1.728 falls in the rejection region where the critical value is -1.725
as only - 1.728 < -1.725
