Answer: the z score is 1
Step-by-step explanation:
Since the head circumference for boys at birth is normally distributed,
we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = head circumference for boys at birth.
µ = mean head circumference
σ = standard deviation
From the information given,
µ = 34.5cm
σ = 1.3 cm
For a boy born with a head circumference of 35.8cm, the z score is
z = (35.8 - 34.5)/1.3
z = 1

Answer:
The dollar amount of the meals Sarah served was $1150.
Step-by-step explanation:
Set up an equation expressing Sarah's total earnings:
(total earned) = (base wage) + 0.15 * (price of meals served)
Now the same using what we know:
$252.50 = $80 + 0.15 * x
where x is unknown and can be solved for:
x = (252.50 - 80) / 0.15 = $1150
The dollar amount of the meals Sarah served was $1150.
