I believe it's George Washington!
Answer:
Between 395 and 435 out of 457 orders are filled accurately.
Explanation:
457 minus 42 makes 415. To this number we have to add the 95% confidence, which means that there is a 5% high and low difference that we have to take in account on the perfect 415 outcome. 5% of 415 is 20.75 so that leads to a maximum low of 395 (415-20) and a maximum high of 435 (415 + 20).
