A researcher calculates is doing a two-tailed test and calculates a test statistic of z=-1.69 and her level of significance (alpha) is 0.05. Does she reject the null hypothesis?
a) Yes
b) No
c) Need more information
Homework Answers
Here,
The value of the test statistic zobs = -1.69
P-value
Since P-value > 0.05 = level of significance (alpha) , so we fail to reject the null hypothesis.
ans-> No
