Using the proportion of defective watches in the sample (3 out of 400), we can calculate the expected number of defective watches in the total population of 10,500 watches:
Expected number of defective watches = (3/400) * 10,500 = 78.75
Therefore, based on this sample data, we would expect approximately 78 defective watches out of the total 10,500 watches.
In a random sample of 400 watches, 3 are defective. Out of a total of 10,500 watches, how
many would you expect to be defective based on this sample data? (1 point)
