o test this model, the biologist collects a sample of $20$ adult marmots. The lengths and weights of the marmots are as

follows:

length $=[22\mathrm{.}7,22\mathrm{.}4,25\mathrm{.}8,21\mathrm{.}3,20\mathrm{.}1,22\mathrm{.}1,21\mathrm{.}1,25\mathrm{.}3,26\mathrm{.}9,26\mathrm{.}9,$

$23\mathrm{.}0,23\mathrm{.}8,26\mathrm{.}2,20\mathrm{.}4,23\mathrm{.}0,21\mathrm{.}9,23\mathrm{.}5,27\mathrm{.}8,25\mathrm{.}3,25\mathrm{.}9]$

weight $=[9\mathrm{.}2,8\mathrm{.}8,10\mathrm{.}7,8\mathrm{.}3,6\mathrm{.}2,8\mathrm{.}6,7\mathrm{.}2,11\mathrm{.}2,10\mathrm{.}5,11\mathrm{.}3,$

$9\mathrm{.}6,9\mathrm{.}9,10\mathrm{.}9,5\mathrm{.}9,9\mathrm{.}5,9\mathrm{.}1,9\mathrm{.}7,11\mathrm{.}6,10\mathrm{.}2,10\mathrm{.}5]$

Create these lists, as the appear here. You do not need to print anything in this cell.

Create a list named pred$\_$weight containing the predicted weight for each marmot, according to the biologist's model.

You should begin by creating pred$\_$weight as an empty list. Then loop over the elements of length. Each iteration of

the loop should calculate a new predicted weight using the formula provided above, and rounded to $2$ decimal places.

The round value for each predicted weight should be appended to the list pred$\_$weight.

Print pred$\_$weight.
