Answer:
Step 1: Put the numbers in order. ...
Step 2: Find the median. ...
Step 3: Place parentheses around the numbers above and below the median. Not necessary statistically, but it makes Q1 and Q3 easier to spot. ...
Step 4: Find Q1 and Q3. ...
Step 5: Subtract Q1 from Q3 to find the interquartile range.
To find the answer just do the opposite-
If you added 10, then you subtract 10.
So 23.69 - 10 = 13.69
If you multiply an number by itself, you are basically doing exponents so do the opposite of exponents which is root square.
So you root square 13.69
Which equals 3.7
So the number is 3.7
