Based on the sample data, the proportion of defective watches in the sample is 3/400.

To estimate the number of defective watches in the total population of 10,500 watches, we can use this proportion:

(3/400) * 10,500 = 78.75

Rounded to the nearest whole number, we would expect approximately 79 watches to be defective out of the total 10,500 watches.
