[Video] Q15: Each of the box plots shown summarizes a data set. data set a has a range of 130, and data set b has a range of 80. if the two data sets are combined into one data set, what is the range of the combined data set?

Explanation for Question 15 From the Math (Calc) Section on the 2020 October Sat

So question number 15 is asking us what happens to the range. 2 If we combine the two datasets, now we see if we combine the two 3 data sets that we're going to get a new minimum and we're going to 4 get a new maximum. The minimum value is going to come from dataset a 5 and it's going to be about 10. 6 And the new maximum value is going to come from dataset B because it 7 has the highest value. It it'll be about one 60 and we know that 8 to find the range. We have to find the difference between the highest and 9 the lowest value. So we should do one 60 minus 10 to find the 10 range and that'll give us 150, 11 which is answer choice C.
