Answer:
The IQR describes the middle 50% of values when ordered from lowest to highest. To find the interquartile range (IQR), first find the median (middle value) of the lower and upper half of the data. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.

Answer:
49
Step-by-step explanation:
This is because 49 is below 50 but above 40. The number must also round to 0 from the nearest 100, so any value 50 and above will round to 100 and any value 49 and below will round to 0. So we are left with the values 40-49 because any value below 40 is rounded to either 40,30,20,10 or 0. Since any value below 45 won't round to 50, any value between 45 and 49 will work.
