Question $13$

Consider the following array:

dataTrial$1=[28\mathrm{.}3,29\mathrm{.}1,28\mathrm{.}4,29\mathrm{.}0,28\mathrm{.}6,28\mathrm{.}7,28\mathrm{.}7,28\mathrm{.}8]$;

What is the value of the following command?

dataTrial$1(2$:$4)$

ans $=29\mathrm{.}100029\mathrm{.}0000$

ans $=29\mathrm{.}000029\mathrm{.}1000$

ans $=29\mathrm{.}100028\mathrm{.}400029\mathrm{.}0000$

ans $=28\mathrm{.}400029\mathrm{.}000029\mathrm{.}1000$
