Question $3$b

$(10)$

Four experiments are performed, each consisting of five test results. The results for each experiment are given in the following list.

$\backslash$table$[[1^{st}$ experiment results:,$23\mathrm{.}2,31,16\mathrm{.}9,27,25\mathrm{.}4],[2^{nd}$ experiment results:,$34\mathrm{.}8,45\mathrm{.}2,27\mathrm{.}9,36\mathrm{.}8,33\mathrm{.}4],[3^{rd}$ experiment results:,$19\mathrm{.}4,16\mathrm{.}8,10\mathrm{.}2,20\mathrm{.}8,18\mathrm{.}9],[4^{th}$ experiment results:,$36\mathrm{.}9,39,49\mathrm{.}2,45\mathrm{.}1,42\mathrm{.}7]]$

$10$

Complete the program below using a nested loop to compute and display the average of the test results for each experiment. Display the average with a precision of two digits after the decimal point.
