The weights of U.S pennies are distributed approximately normal with a mean of 2.5 grams and a standard deviation of 0.03 grams. What is the proabbility that a randomly chosen penny weighs less than 2.49 grams? What is the probability that the average weight in a sample of 100 pennies is less than 2.49 grams? Could you estimate the probability that a randomly chosen penny weighs less than 2.49 grams using a normal curve if the weights of pennies had a skewed distribution? Could you estimate the probability that a the average weight in a sample of 100 pennies is less than 2.49 grams using a normal curve if the weights of pennies had a skewed distribution?
