Step 1 ：Calculate the probability of a newborn baby weighing between 4 and 7 pounds using the normal distribution with a mean of 6.7 pounds and a standard deviation of 1.5 pounds
Step 2 ：Multiply this probability by the total number of babies (800) to get the expected number of babies in that weight range
Step 3 ：Final Answer: \(\boxed{435}\)
