Answer: The cars from Company A have a higher mean highway fuel efficiency than Company B.

Work:
- Company A: mean = (35+28+35+30+31+38+35+30)/8 = 262/8 = 32.75; median = (31+35)/2 = 33; mode = 35.
- Company B: mean = (29+33+36+27+34+34+34+25)/8 = 252/8 = 31.5; median = (33+34)/2 = 33.5; mode = 34.

Thus statement 2 is true.
