The weights of newborn babies are distributed normally, with a mean of approximately 105 oz and a standard deviation of 10 oz. if a newborn baby is selected at random, what is the probability that the baby weighs more than 75 oz

0.9987

Step-by-step explanation:

Given : The weights of newborn babies are distributed normally, with a mean of approximately 105 oz and a standard deviation of 10 oz.

i.e.  and

Let x represents the weights of newborn babies.

If a newborn baby is selected at random, then the probability that the baby weighs more than 75 oz will be :-

  [using z-value table]

Hence, the required probability = 0.9987
