given:
mean, pounds
standard deviation, pounds
a normal distribution formula:
1. How many would you expect to weigh between and pounds?
=
=
=
=
=
=% => answer
Consider a group of newborn babies, then ≈ babies expected to weigh between and pounds
2. How many would you expect to weigh less than pounds?
%=> answer
≈ babies expected to weigh less than pounds
3. How many would you expect to weigh more than pounds?
% => answer
≈ babies expected to weigh more than pounds
4. How many would you expect to weigh between and pounds?
=
=
=
=
=
=% => answer
≈ babies expected to weigh between and pounds
