Suppose the ages of multiple birth (3 or more babies) are normally distributed with a mean age of 31.7 years and a standard deviation of 5.2 years. what percent of these mothers are between the ages 30-35

The percent of these mothers are between the ages 30-35 is 36.53%

Step-by-step explanation:

we are given

mean of age =31.7 years

standard deviation of 5.2 years

For age=30 years:

x=30

we can find z-score

we can plug values

For age=35 years:

x=35

we can find z-score

we can plug values

now, we can use normal distribution table

now, we can find percentage

=36.53%
