II$.$ Future recognition from surface models of complicated parts is becoming increasingly important in the development of an efficient computer$-$aided design $($CAD$)$ system. The followings are the summary statistics and stem$-$and$-$leaf plot for the number of edges $($EDGES$)$ of a part and the recognition time $($TIME$)$ in seconds recorded to examine the relationship between them.Answer the following questions $(1)-(3)$ using the information above. Select one choice for each question.

$(1)$ What is the I.Q$.$R$.($or the fourth spread$)$ for EDGES data? Choose the best answer.

$($a$)10\mathrm{.}37$

$($b$)20\mathrm{.}42$

$($c$)30\mathrm{.}70$

$($d$)40\mathrm{.}53$

$(2)$ Which of the followings is not correct? $\text{'}$s

$($a$)$ The median of EDGES data is larger than the one of TIME data.

$($b$)$ The I.Q$.$R$.$ of TIME data is less than the one of EDGES data.

$($c$)$ The Q$1\text{'}$s of both EDGES and TIME data are the same.

$($d$)$ Both EDGES and TIME data are skewed to the right.
