Suppose You Wish to Transmit a Stereo Audio Signal Through $44.1 \mathrm{kHz}$

Suppose you wish to transmit a stereo audio signal through a 1 mega-bit/s connection in real time. Consider the following scenarios:
i) You are using a sampling frequency of $44.1 \mathrm{kHz}$ . What is the maximum average number of bits can you use to represent an audio sample?
ii) You want to use $16 \mathrm{bit} / \mathrm{sample} / \mathrm{channel}$ representation. What is the maximum sampling frequency? What will you need to do in order to avoid aliasing?
iii) You want to use a sampling frequency of $44.1 \mathrm{KHz}$ , and also want use $16 \mathrm{bit} / \mathrm{sample} / \mathrm{channel}$ representation. What is the minimum compression ratio you need in order to transmit the audio signal?
