Explanation:

Z score is determined by

$=\frac{x-u}{SD}$

A) For 33 Week baby

Mean $= 2500$

SD $= 800$

$x=2600$

$\frac{2600-2500}{800} \\= 0.125$

B) For 41 Week baby

Given

Mean $= 2800$

SD $= 425$

$x=2900$

Z score is

$\frac{2900-2800}{425} \\= 0.235$

The z score depicts that the baby of 33 week or 41 week weighs more than the normal babies of same age group.
