Find the level of t needed to construct a twosided confidenc

Find the level of t needed to construct a two-sided confidence interval of the given level with the given sample size:

1. Level 98%, sample size 10.

2. Level 80%, sample size 14.

3. Level 90%, sample size 20.

4. Level 95%, sample size 10.

Find the level of a two-sided confidence interval that is based on the given value of t and the given sample size:

1. t = 1.943, sample size n = 7.

2. t = 2.093, sample size n = 20.

3. t = 1.753, n = 16.

Find the level of t needed to construct a two-sided confidence interval of the given level with the given sample size:

1. Level 98%, sample size 10. t= 2.821

2. Level 80%, sample size 14. . t= 1.350

3. Level 90%, sample size 20. . t= 1.729

4. Level 95%, sample size 10. . t= 2.262

Find the level of a two-sided confidence interval that is based on the given value of t and the given sample size:

1. t = 1.943, sample size n = 7.

Level =90%

2. t = 2.093, sample size n = 20.

Level =95%

3. t = 1.753, n = 16.

Level =90%
