Probability with Applications in Engineering, Science, and Technology (precalculus, calculus, Statistics)

Determine the $t$ critical value for a one-sample $t$ confidence interval in each of the following

situations.

(a) Confidence level $=95 \%, \mathrm{df}=10$

(b) Confidence level $=95 \%, \mathrm{df}=15$

(c) Confidence level $=99 \%, \mathrm{df}=15$

$\begin{array}{ll}{\text { (d) }} & {\text { Confidence level }=99 \%, n=5} \\ {\text { (e) }} & {\text { Confidence level }=98 \%, \text { df }=24} \\ {\text { (f) }} & {\text { Confidence level }=99 \%, n=38}\end{array}$
