1.
A
pediatric nurse is studying the number of babies born at a hospital
with congenital

congenital
defect is born per month.
a. Find the probability that at least two babies are born
with congenital defects in one year.
b. Find the probability that exactly twelve or exactly fifteen
babies are born with congenital defect in five months.

A pediatric nurse is studying the number of hours infants sleep
daily. He reviewed data from eight randomly selected patients from
the pediatric ward of the local hospital. The results were as
follows, where x is the infant’s age in months, and y is the number
of hours the infant slept daily: \
X 2 1 7 6 14 15 10 9
Y 14.50 15.00 14.25 13.5 12.75 12.00 13.25
