A manufacturer produces 54-pound lifting weights. The lowest actual weight is 40 pounds, and the highest is 74 pounds. Each weight is equally likely so the distribution of weights is uniform. A sample of 49 weights is taken a) What is the distribution for the weights of one 54-pound lifting weight? Select an answer v What is the mean and standard deviation ? (Round to four decimal places) b) What is the distribution for the mean weights of 49 54-pound lifting weight? Select an answer v What is the mean and the standard deviation of (Round to four decimal places)
