I am struggling with finding the confidance interval. for example, A banker wants to know the mean amount of mortgage paid per month by homeowners in an area. A random sample of 118 homeowners selected from this area showed that they pay an average of $1579 per month for their mortgages. The population standard deviation of such mortgages is $211.
