Question
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)
watches
Based on the sample data, we can calculate the proportion of defective watches in the sample: 3 / 400 = 0.0075.
To estimate the number of defective watches in the total population of 10,500 watches, we can use this proportion: 0.0075 * 10,500 = 78.75.
Therefore, we would expect approximately 78 or 79 watches to be defective out of a total of 10,500 watches based on this sample data.
