Answer:

Given data set is 17,16,25,23,22,23,28,25,25,23

Arranging the data set in ascending order we get 

16,17,22,23,23,23,25,25,25,28

Total number of values is 10

Mean is 116+17+22+23+23+23+25+25+25+28 divide by 10 =10227=22.7

Median is the middle value i.e., 5th+6th value divede by 2 is the median.

Therefore median is 23+33 divide by 2 =23

The empirical formula is mode=3median−2mean

⟹mode=3(23)−2(22.7)=69−45.4=23.6
