The mean weight of 15 randomly selected newborn babies at a local hospital is 7.84 lbs and the standard deviation is 0.2 lbs. Assume the weight of newborn babies has approximately normal distribution. (a) Find the margin of error for the 95% confidence interval for the mean weight of all newborn babies at this hospital. (Round your answer to two decimal places.) (b) Use information from part (a) to fill in the banks in the following sentence: V o % of all samples of size 15 o have sample means 95 within Ibs of the population mean. (Rounc
