15 During a cold winter, the temperature stayed below zero for ten days (ranging from -20 to -5). The variance of the temperatures of the ten-day period A must be less than 15 since the range is equal to 15 B. None of the suggested answers are correct should not be used since it is against logic to compute squared deviation from a negative mean must be about zero to adjust for negative and positive temperature values
