There is insufficient evidence to warrant rejection of the claim that the three different miles have the same mean ride time. Does one of the miles appear to have a hill? O A. Yes, these data suggest that the third mile appears to take longer, and a reasonable explanation is that it has a hill. O B. Yes, these data suggest that the second mile appears to take longer, and a reasonable explanation is that it has a hil. O C. No, these data do not suggest that any of the miles have a hill.
