Consider a sample of rubber bands. Their weights are measured and found to have a variance of 2.57. Give a point estimate for the population variance in weights of rubber bands. Round your answer to two decimal places, if necessary.

The weights of broilers (commercially raised chickens) are approximately normally distributed with mean 1387 grams and standard deviation 161 grams. what is the probability that a randomly selected broiler weighs more than 1,425 grams?
