Question 934196: A researcher carried out a hypothesis test using a two-tailed alternative hypothesis. Which of the following z-scores is associated with the smallest p-value.
Z= -0.41 z= 1.48 z= -2.24 z = 2.79
Which z-score has the smallest p value and why?
thank you!

You can put this solution on YOUR website! A researcher carried out a hypothesis test using a two-tailed alternative hypothesis. Which of the following z-scores is associated with the smallest p-value.
Z= -0.41 z= 1.48 z= -2.24 z = 2.79
Which z-score has the smallest p value and why?
----------
z = -0.41:: implies p-value = 2normalcdf(-100,-0.41) = 0.68
---
z = 1.48:: implies p-value = 2normalcdf(1.48,100) = 0.13887
----
z = -2.24:: implies p-value = 2normalcdf(-2.24,-100) = 0.025
---
z = 2.79:: implies p-value = 2normalcdf(2.79,100) = 0.005
----
Ans:: z = 2.79
