A study of lobster trap placement used a 90​% confidence interval to estimate the mean trap spacing​ (in meters) for the population of red spiny lobster fishermen fishing in the west coast. How many teams of fisherman would need to be sampled in order to reduce the width of the confidence interval to 4 ​meters? Assume prior knowledge indicates that the trap spacing readings for the population of red spiny lobster taken during a day are approximately normally distributed with a standard deviation of 12.7 meters. The experiment must sample how many teams of fisherman in order to reduce the width of the confidence interval to 4 meters? ​(Round up to the nearest whole​ number.)
