1.
In the country of United States of Heightlandia, the height
measurements of ten-year-old children are approximately normally
distributed with a mean of 55.7 inches, and standard deviation of
1.7 inches.
What is the probability that the height of a randomly chosen child
is between 53.05 and 53.95 inches? Do not round
until you get your your final answer, and then round to 3 decimal
places.
Answer= (Round your answer to 3 decimal places.)
2.
The mean daily production of a herd of cows is assumed to be
normally distributed with a mean of 35 liters, and standard
deviation of 4.2 liters.
A) What is the probability that daily production is
less than 26.8 liters?
Answer= (Round your answer to 4 decimal places.)
B) What is the probability that daily production is
more than 24.9 liters?
Answer= (Round your answer to 4 decimal places.)
Warning: Do not use the Z Normal Tables...they may not be accurate
enough since WAMAP may look for more accuracy than comes from the
table.
