Question

The weights for newborn babies is approximately normally distributed with a mean of 5.4 pounds and a standard deviation of 1.8 pounds. Consider a group of 1500 newborn babies: 1. How many would you expect to weigh between 3 and 6 pounds

Answer 1

Answer:

You would expect 807 babies  to weigh between 3 and 6 pounds.

Step-by-step explanation:

We are given that

Mean,$\mu=5.4$pounds

Standard deviation,$\sigma=1.8$pounds

n=1500

We have to find how  many would you expect to weigh between 3 and 6 pounds.

The weights for newborn babies is approximately normally distributed.

Now,

$P(3$

$=P(-1.33$

$P(3$

$P(3$

$P(3$

Number of newborn  babies expect to weigh between 3 and 6 pounds

=$1500\times 0.538=807$
