In the ponds at Magnusson Park, UW students randomly measured the weight (in pounds) of 12 adult beavers, with a mean of 47 lbs and a standard deviation of 5 Ibs. A previous study found that beavers across Washington state typically weigh 44 Ibs. Adult beaver weights tend to be normally distributed. Is the average weight for the Magnusson Park beavers what you would expect, given what you know about Washington beavers?
