Answer to Question #343130 in Statistics and Probability for Rhea

Question

Activity 1 Find the critical value of the following

Lone-tailed test, or known, a= 0.05; n = 34,

2 two-tailed iest, a unknown, a = 0.01, n=23

3 night-tailed test, a unknown; a = 0.01, n = 15

4 one-tailed test, a known, a = 0.025; n = 37

5 left-tled test, a known, a= 0.05, n = 36

Answer 1

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

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

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

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

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

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

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

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