Answer

Average:159.8 million, no mode, median: 95 million, midrange:199.5 million. The only thing that is for sure that the averge salary of all celebraties must be less than 159.8 million.

Work Step by Step

The average can be counted by summing all the data and dividing it by the number of data: $\frac{332+302+235+225+100+90+88+84+75+67}{10}=159.8$, the average earning is 159.8 million. The mode is the data occuring the most times but here all data occurs one time, therefore there is no mode. The median is the average of the 1 or 2 (here 2) middle data: (100+90)/2=95, the median is 95 million. The midrange is the average of the highest and the lowest data: (332+67)/2=199.5, the midrange is 199.5 million. The only thing that is for sure that the averge salary of all celebraties must be less than 159.8 million.
