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.
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?
__ watches
