Problem: Nonresponse. Academic sample surveys, unlike commercial polls, often discuss nonresponse. A survey of drivers began by randomly sampling all listed residential telephone numbers in the United States. Of 45,956 calls to these numbers, 5029 were completed.
Required:
What was the rate of nonresponse for this sample? (Only one call was made to each number. Nonresponse would be lower if more calls were made.)
A person wears a hearing aid that uniformly increases the intensity level of all audible frequencies of sound by 32.5 dB. What is the intensity delivered to the eardrum
Consider again the long wire near a small wire rectangle. The long wire is part of a circuit. The circuit is small enough that all the approximations we've used in class are good, but the wire near the rectangle is much longer than the rectangle. ..
