Select the correct choice below and fill in the answer box to complete your choice Type a whole number.) O A. The probability is 0.0228 that the birth weight of a randomly chosen full-term baby in this population is less than grams O B. The probability is 0.0228 that the birth weight of a randomly chosen full-term baby in this population is more thangrams

Answer 1

a)

option B) is the correct graph

b)

mean = 3600 , sigam = 480

P(x > 4560)
= 1- P(z < (x - mean)/sigma)
= 1 - P(z < (4560 - 3600)/480)
= 1 - P(z < 2)
= 1 -0.9772
= 0.0228

option B) is the corrrect graph

c)

B) The probability is 0.0228 that the birth weight of a randomly chosen full term body in this population is more than 4560 grams
