A random sample of 1,584 people that work in a particular high-rise building are normally dis tributed, have a mean of 165 pounds with a population standard deviation of 30 pounds. Determine if the information can be used to create a confidence interval. If so, find the 97% confidence inter- val for the average weight of someone living in this high-rise. If not, give a detailed explanation as to why this information does not fit the definition.
