A worker takes a random sample of 290 bolts and finds that 29 of them are either too long or too short, thus making them unusable. Estimate the number of unusable bolts in a production of 20,000 bolts.

i think 2,000 because for every 10 bolts one of them is going to be unusable and 20,000 divided by 10 is 2,000

29/290 = 0.1
0.1 * 20,000 = 2,000
There will be 2,000 unusable bolts. I hope this helps :)
