Answer:
a) 0.3277
b) 0.0128
Step-by-step explanation:
We are given the following information in the question:
N(2750, 560).
Mean, μ = 2750
Standard Deviation, σ = 560
We are given that the distribution of distribution of birth weights is a bell shaped distribution that is a normal distribution.
Formula:

a) P (less than 2500 grams)
P(x < 2500)

Calculation the value from standard normal z table, we have,

b) P ((less than 1500 grams)
P(x < 1500)

Calculation the value from standard normal z table, we have,

.06*120=$7.20
.005*44=$0.22
The slope of a line is the difference between the x-line and the y-line. Rise/run
A - This is the same as : (3*3*3*3)/4 Wrong.
B - This is 12/4 Wrong.
C- This is 3/2 * 3/2 * 3/2 * 3/2 Correct.
