You are performing a left-tailed z-test If α = .05 , find the critical value, to two decimal places.
Z critical value is -1.64..........................by using =NORMSINV(0.05) in Excel or by using Z table.
Therefore, for left tailed z test and α = .05
Z critical value is -1.64
Z critical value is -1.64..........................by using =NORMSINV(0.05) in Excel or by using Z table.
Therefore, for left tailed z test and α = .05
Z critical value is -1.64

You are performing a left-tailed t-test with a sample size of 21. If α=.05α=.05, and your test statistic is t=−2.89t=-2.89, do you: fail to reject the null hypothesis reject the null hypothesis You will either want to either: Calculate the critical value and compare the test statistic to it. Calculate the p-value and compare it to the significance.
