Question 1
Consider a significance test for a null hypothesis versus a two-sided alternative with az-test statistic. Give a value ofz that will give a result significant at the 1% level but not at the 5% level.
◦
z= 1.96
◦
z= –2.57
◦
z= 3.98
◦
There is no suchz-value.

◦
z= 1.645
◦
z= –2.17
◦
z= –2.65
