A CD quality stereo digital sound sample has a size of 25000000
bytes. What is the duration of this sample? Calculate your answer
in seconds. Do not enter any unit.
Homework Answers
rate = quantity / duration
duration = quantity / rate
The CD recording rate per channel is 44.1kHz, with each sample
being 16 bits in size. Since this is specified as stereo, there are
two channels.
and
8 bit = 1 byte
duration = 25000000 bytes / (44.1k samples/second * 16bits/sample *
1byte/8bits * 2 channels)
duration = 141.72 second

The following data show the brand, price ($), and the overall score for six stereo headphones that were tested by a certain magazine. The overall score is based on sound quality and effectiveness of ambient noise reduction. Scores range from 0 (lowest) to 100 (highest). The estimated regression equation for these data is ŷ = 20.455 + 0.335x, where x = price ($) and y = overall score. Brand Price ($) Score A 180 78 B 150 69 C 95...
