Answer:
The birth weight associated with the lowest 1% is 4.6 pounds.
Step-by-step explanation:
Let <em>X</em> represent the birth weights of babies.
It is provided that 
It is also provided that many pre-mature births weights are in the lowest 1% of births.
Let <em>x</em> represent the births weights that are in the lowest 1% of births.
That is, P (X < x) = 0.01.
⇒ P (Z < z) = 0.01
The corresponding <em>z</em>-score is, <em>z</em> = -2.33.
Compute the value of <em>x</em> as follows:

Thus, the birth weight associated with the lowest 1% is 4.6 pounds.
Answer:
The difference is $5.62
Step-by-step explanation:
The total cost Marcus will pay is
35.99 + 5.5% of 35.99
= 35.99 + 0.055(35.99) = 35.99 + 1.97945 = 37.96945
The total cost Tai will pay is;
39.99 + 9% of 39.99
= 39.99 + 0.09(39.99) = 43.5891
The difference between the total costs will be;
43.5891 - 37.96945 = 5.61965
To the nearest cent, this is 5.62
