The distribution of weights for newborn babies is approximately normally distributed with a mean of 7.3 pounds and a standard deviation of 0.6 pounds.

The required probability will be "0.16".

Explanation:

The one standard deviation above the mean will be:

⇒

As per the usual distribution empirical principle or theorem, 68 percent including its measurements fall within the same standardized deviation from the mean that would be 32 percent just outside of the limit, implying that

=

=

Including its observations lie from an outside distance along both sides.
