A population consists of a batch of 24,703 aspirin​ tablets, and it includes 920 that are defective because they do not meet specifications. A random sample of n=280 of the tablets is obtained and​ tested, with the result that 20 of them are defective.

a. What is the population​ proportion, p, of defective aspirin​tablets?

b. what is the sample proportion,p, of defective tablets?

c. How can the discrepancy between the population proportion and the sample proportion be​ explained?
