In a random sample of 30 young bears, the average weight at the
age of breeding is 312 pounds. Assuming the population ages are
normally distributed with a population standard deviation is 30
pounds, use the Empirical Rule to construct a 68% confidence
interval for the population average of young bears at the age of
breeding. Do not round intermediate calculations. Round only the
final answer to the nearest pound. Remember to enter the smaller
value first, then the larger number. Provide your answer below:
