A two-way frequency table is shown below that displays the relationship between television technology type and television size sold at a local retail outlet. Store managers took a sample of 90 people and recorded the following results:
 

  Plasma TV LCD TV Projection TV Total
54 inches 20 8 2  
68 inches 9 22 2  
86 inches 6 16 5  
Total       90



The retail outlet is putting its LCD televisions on sale. Given this information, what percent (rounded to the nearest whole percent) of the warehouse should be stocked with 86-inch televisions?

 

 

A 35%

B 18%

C  59%
