Psychologists want to estimate the mean attention time given to twins per week by their parents. A sample of 86 sets of twin boys is taken and the attention time given to them by their parents in a week is recorded. The results are a mean time of 33.71 hours with a standard deviation of 5.33 hours. Construct a 99% confidence interval for the population mean attention time given all twins.
