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 7 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 12.1 meters The experiment must sample ______ teams of fisherman in order to reduce the width of the confidence interval to 7 meters (Round up to the nearest whole number.)
