Based on data from a large study of healthy infants in six countries, the world health organization produced growth charts that are part of every pediatrician’s toolkit for monitoring a child’s overall health. according to the who report, girls who are one month old have a mean head circumference of 36.6 centimeters with a standard deviation of 1.2 centimeters. as with most body measurements, head circumference has a normal probability distribution. medscape defines microcephaly (small head syndrome) as a head circumference that is more than two standard deviations below the mean. what is the probability that a one-month old girl will be categorized as having microcephaly?

1.1375%

Step-by-step explanation:

If the measurements follow a normal distribution, then

100%-95.45% = 4.55%

must be outside the interval  

[mean-2 times standard deviation, mean+2 times standard deviation]

= [36.6-2(1.4), 36.6+2(1.4)]

(see picture attached)

Of this 4.55%, 2.275% is less than 36.6-2(1.4) (microcephaly) and 2.275% is greater than  36.6+2(1.4) (macrocephaly)

Supposing half of these children are girls, we have a probability of 1.1375%

So, the probability that a one-month old girl will be categorized as having microcephaly is 1.1375%, that is to say 11,375 one-month-old girls out of 1,000,000 will probably be categorized as  having microcephaly.

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
