Answer 1

Answer:

(a) 10% of 36 ­month ­old males weigh 11.0 kg or less, and 90% of 36 ­month ­old males weigh more than 11.0 kg.

(b) 90% of newborn females have a length of 54.3 cm or less, and 10% of newborn females have a length that is more than 54.3 cm.

Step-by-step explanation:

(b) Similarly to the last item, if the 90th percentile of the length distribution is 54.3 cm, then 90% of newborn females in the city measure 54. 3 cm or less while 10% measure more than 54.3 cm.
