What is the probability that the 25 babies are born with a mean weight less than 3100g? What are the parameters? Construct the normal distribution density curve; then shade the seeking area. Find the z-score; and construct, then shade the seeking area on the standard normal distribution density curve. Find the probability.

Step 1
The standard deviation is also not given, so we assume it to be 150g (a common value for newborns). μ = 3100g (mean weight) σ = 150g (standard deviation) Show more…

Babies' birth weights are normally distributed with mean 120 ounces and standard deviation 20 ounces. what is the probability that a baby weighs between 85 and 155 ounces?

If 25 newborn babies are randomly selected, what is the probability that the 25 babies are born that their mean weigh less than 3100g?
T. L.
Suppose that birth weights are normally distributed with a mean of 3466 grams and a standard deviation of 546 grams. Babies weighing less than 2500 grams at birth are considered "low weight." If we randomly select a baby, what is the probability that it has a low birth weight? 0.0177 about 2% 0.0384 about 4% 0.9616 about 96%
