1. Based on the information provided, the significance level is α=0.05,\alpha = 0.05,

the critical value for a left-tailed test is zc=1.6449,z_c = -1.6449, the critical value for a right-tailed test is zc=1.6449.z_c = 1.6449.


2. Based on the information provided, the significance level is α=0.01,\alpha = 0.01, df=n1=22df=n-1=22 degrees of freedom, and the critical value for a two-tailed test is tc=2.624494.t_c = 2.624494.


3. Based on the information provided, the significance level is α=0.01,\alpha = 0.01, df=n1=14df=n-1=14 degrees of freedom, and the critical value for a right-tailed test is tc=2.818756.t_c = 2.818756.


4. Based on the information provided, the significance level is α=0.025,\alpha = 0.025,

the critical value for a left-tailed test is zc=1.96,z_c = -1.96, the critical value for a right-tailed test is zc=1.96.z_c = 1.96.


5. Based on the information provided, the significance level is α=0.05,\alpha = 0.05,

the critical value for a left-tailed test is zc=1.6449.z_c = -1.6449.
