Jerome asked 19 people to install an app that recorded the
amount of time that they spent on their phones each day and found
an average of 279 minutes. From earlier studies, he assumes that
times are normally distributed with standard
deviation σ=41 minutes. Calculate a 96% confidence
interval for the population mean. Round the endpoints to the
nearest minute.
