為了培養(yǎng)學(xué)生的環(huán)境保護(hù)意識(shí),某校組織課外小組對(duì)該市做空氣含塵調(diào)查,下面是一天每隔2小時(shí)測(cè)得的數(shù)據(jù):0.03,0.04,0.03,0.02,0.04,0.01,0.030.03,0.04,0.05,0.010.03(單位:g/m3

1)求出這組數(shù)據(jù)的眾數(shù)和中位數(shù);

2)若國(guó)家環(huán)保局對(duì)大氣飄塵的要求為平均值不超過(guò)每立方米0.025g,問(wèn)這天該城市的空氣是否符合國(guó)家環(huán)保局的要求?

 

答案:
解析:

1)眾數(shù)和中位數(shù)都是0.03
