Answer #1

(a)

Total frequency = 147 + 328 + 551 + 1143 + 2427 = 4596

Response	Probability
Never	147/4596 = 0.032
Rarely	328/4596 = 0.071
Sometimes	551/4596 = 0.120
Most of the time	1143/4596 = 0.249
Always	2427/4596 = 0.528

(b)

Since the probability that a college student never wears a belt is very low (less than 0.05), we can consider it as unusual.
