(See Solution) The mean weight of 25 randomly selected newborn babies at a local hospital was found to be 7.30 lbs. and the standard deviation was found
Question: The mean weight of 25 randomly selected newborn babies at a local hospital was found to be 7.30 lbs. and the standard deviation was found to be 0.75 lbs. If the weights of newborn babies is approximately normally distributed (20 points)
- Find a 95% confident interval for the average weight of all newborn babies at this hospital
- If you increase the sample size, will the confident interval estimate be wider or narrower ?
