Answer:
Q₃ = 185
Explanation:
the first step is to find the median of the data set
the median is the middle value of the data arranged in ascending order
112 , 130 , 132 , 140 , 149 , 151 , 163 , 172 , 185 , 190 , 200
↑ middle value
median = 151
the upper quartile Q₃ is the middle value of the data to the right of the median
163 , 172 , 185 , 190 , 200
↑ middle value
upper quartile Q₃ = 185
