Temperature transducers of a certain type are shipped in batches of 50. A sample of 60 batches was selected, and the number of transducers in each batch not conforming to design specifications was determined, resulting in the following data: 0 5 3 1 1 2 4 0 1 3 042 1 3 1 1 2 3 3 1 3 2 470 3 2 28 4 4 1 4 1 2 2458 2 3 3 1 6 0 3 3 3 6 12 2 50 2 3 2 1 0 6 2 1 USE SALT (a) Determine frequencies and relative frequencies for the observed values of x = number of nonconforming transducers in a batch.
