Wildlife conservationists studying grizzly bears in the United States found that the mean weight of 24 adult males was 668 pounds with a standard deviation of 81 pounds. Construct a 95% confidence interval for the mean weight of all adult male grizzly bears in the United States. Assume that the weights of all adult male grizzly bears in the United States are normally distributed. Round to the nearest whole number.
