The average temperatures of the highest and lowest temperatures are: (12+14+22+24+27+25+23)÷7=21, (3+6+112+16+18 +18)÷7=1167,
The variance of the maximum temperature=17[(12-21)2+(14-21)2+…+(23-21)2]=28,
p>The variance of the minimum temperature=17[(3-1167)2+(6-1167)2+…+(18-1167)2]=1648,
∵The variance of the maximum temperature It is smaller than the variance of the minimum temperature,
∴The maximum temperature is relatively stable.
So fill it high.
