How much difference do a couple of weeks make for birth weight? late-preterm babies are born with 34 to 36 completed weeks of gestation. the distribution of birth weights (in grams) for late-preterm babies is approximately n(2750, 560).
1. what is the probability that a randomly chosen late-preterm baby would have a low birth weight (less than 2500 grams)? round your answer to 4 decimal places.
2. what is the probability that a randomly chosen late-preterm baby would have a very low birth weight (less than 1500 grams)? round your answer to 4 decimal places.

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,  

add 5 subtract 1

step-by-step explanation:

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
