The Answer is t_n_-1,_α_/2 s/ tn-1,α/2 s/ = (68.52 - 58.62)/ 2 = 4.95 ⇒ t34,α/2 = 4.95 ⇒ t34,α/2 = 1.69. Hence,α/2 = 0.05,or α = 0.10.Then the confidence level is 90%.

t<sub>n</sub><sub>-1,</sub><sub>α</sub><sub>/2</sub> s/ = (68.52 - 58.62)/ 2 = 4.95 ⇒ t<sub>34,</sub><sub>α</sub><sub>/2</sub><sub> </sub> <sub> </sub> = 4.95 ⇒ t<sub>34,</sub><sub>α</sub><sub>/2</sub> = 1.69. Hence,α/2 = 0.05,or α = 0.10.Then the confidence level is 90%.

= (68.52 - 58.62)/ 2 = 4.95 ⇒ t_34,_α_/2

tn-1,α/2 s/ = (68.52 - 58.62)/ 2 = 4.95 ⇒ t34,α/2 = 4.95 ⇒ t34,α/2 = 1.69. Hence,α/2 = 0.05,or α = 0.10.Then the confidence level is 90%.

= 4.95 ⇒ t_34,_α_/2 = 1.69.
Hence,α/2 = 0.05,or α = 0.10.Then the confidence level is 90%.
