Question 1 POST OFFICE ccording to a USPS study, the weight of a randomly selected shipment box has unknown distribution with a ean of 22.7 lbs and a standard deviation of 4.5 lbs. Let X be the weight of a randomly selected shipment ox and let S be the total weight of a random sample of size 9. Describe the probability distribution of X and state its parameters and o: X~ ~Select an answer (f: Select an answer B unknown T F N x² I J = nd find the probability that the weight of a randomly selected shipment box is between 12 and 13 lbs. (Round the answer to 4 decimal places) . Explain why the Central Limit Theorem cannot be used Select an answer Select an answer the original population is normally distributed although the sample size is small (n<30) the sample size is small (n<30) and the distribution of the original population is unknown the original population is normally distributed and the sample is large (n>30) the sample size is large (n>30) although the distribution of the original populaiton is unknown
