A record of $20$ random samples for undrained shear strength of marine clay is listed

below.

Calculate the tolerance interval that capturing at least $95\%$ of the clay undrained

shear strength with a $90\%$ confidence level.

$19\mathrm{.}57$ to $24\mathrm{.}83$

$9\mathrm{.}21$ to $35\mathrm{.}19$

$10\mathrm{.}01$ to $34\mathrm{.}31$

$7\mathrm{.}78$ to $36\mathrm{.}6$
