Step-by-step explanation:
to find the mean add all the numbers up and then divide it by the total number sampled
so we have
(198+199*3+200*2+201*5+202*2)/13
which gives you around 200.3
To find the height of the new player we have the following equation
let x be the height of the new player

solve for x and get
210 cm
