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 o 410 minutes. Calculate a 96% confidence interval for the population mean. Round the endpoints to the nearest minute. Confidence interval: 91 (Remember to round to the nearest minute!)
