B. find the critical value for the test of significance in each of the given information
1.one-tailed test, g? is known a = 0.05. m = 34
2. two-tailed test, g? is known, a = 0.05. n = 45
3. one-tailed test, g? is unknown. a
= 0.05. n= 14
4. two-tailed test, g? is unknown, a = 0.05, n = 10
5. one-tailed test, o? is known a = 0.01. n = 40
6. two-tailed test, o? is known, a :
= 0.01. 2 = 50
7. one-tailed test. g? is unknown a = 0.01.7=16
8. two-tailed test, o? is unknown, a = 0.01, 7 = 9
9. one-tailed test. g? is known a = 0.01.7 = 38
10. two-tailed test, g? is unknown, a = 0.1. n = 12
