So for this question, you want to classify each child into healthy growth rate or possible sign of malnutrition.
00:07
The criteria is that if a kid has healthy growth weight by a year, first birthday, weight weight should be triple the birth weight and the length increased by 50 % which means 150 % multiplied by birth.
00:50
So with this criteria we can actually put kids into each category.
00:55
Let's look at vincent.
01:01
So birth weight 6 lb 10 oz which is 6 .625.
01:11
So expected weight by first birthday 6 .625 multiplied by 3, 19 .875.
01:22
And expected length is birth length 150 % is 1 .5 27 inches now this is greater than its actual weight of 16 point 16 point three one two five pound and also longer than its actual length and because of this we think that vincent might have a possible sign of malnutrition because it's not making it to the expected weight of 19 .875 now let's move on to the second kid lindsey lindsay has a birth weight of 7 .3125 x 3.
02:39
So expected weight is 21 .9375 pounds.
02:48
Expected length is the birth 20 .5 x 1 .5 30 .75 now actual weight is 22 .125 pounds so the expected weight is less than its actual weight 22 .125 and the the actual length is 31, so it's again less than her actual weight.
03:29
So this means that lindsay has a healthy growth rate...
